First of all, thanks for the positive feedback.
Please note that after being a hacker myself - proficiency in other specific sectors not about smartphone OS, yet - I am also specifically educated in project, product delivery and business managements. This brings into the picture a complete different perspective.

In fact, I highlight a particular phrase in your statment above. Sometimes, there is not a solution that fits 100% of requisites or said in another words there is not the perfect solution. Debating for ages about how to implement something is a waste of time, resources and in particular brings to the failure in delivering a product.
-
On the other side the debate, positive and costructive, is also the reason because open source solutions are much better than the proprietary counterparts. The numbers of people and PoVs involved are much higher, many more contributions, etc.
Unfortunately, the statment #2 (positive contribution by many) contrasts with the statmente #1 (need for delivery a product). In the Linux kernel community this contrast have been solved letting Linux Towards performing the role of guide. This role has been granted along decades because he knows how to deliver a product.
OVERVIEW
You may argue that delivering a product does not matter for the community. I agree that many people overlook this aspect. Unfortunately, missing this point fails to encurage the adoption of the technology (SFOS) or blocks it completely. Without a relatively fast adoption curve and large adoption share of a technology (SFOS) every related business strives to survive and on the long run are doomed to fail.
Again, you might not care about business expecially if it is others people business. Unfortunately, others people business can/might be our own business as much as our goals are aligned or complementary.
All of these is about product management. Not about the leadership, not about the community, not about the business. It is about winning or losing the refering market (previosly written as technology adoption rate and share).
This also means that Russian and Chinese people have not a trustful OS to use for their everyday life unless they are hackers. The same for Sirian and Ukrainian people like everyone living in a battle field or in a nation at war.
So, you might not care about Jolla business or about product delivery but you should consider that missing to align/complement with these two “value propositions” also means leaving all those people above in the cold, unless another viable solution exists until it cope to exist (competitor product/offer).
You might hate words like “business”, “product”, “marketing”, etc. and I understand your point of view. I invite you to reconsider that this words are just tools not aims.
These tools can be used for the good or for the bad, either. Instead, ignoring these word or even worse contrast these tools brings nowhere. Nowhere is a place in which everybody feel safe because every confrontation and every effort is meaningless but just self-complacent. The same gap between having sex with others and sex with themselves.
CONCLUSION
Those - who got the real meaning of my overview (named vision in the companies), the deep implications of it and the transparency/clarity in which I expose it without trying to fool people but acknolege them - are prone to accept and complete tasks necessary to deliver a product.
That solutions might not be the best and the perfect solution may not exists either
Under these condition an “arbitrary” decision should be taken or ages passed in vain. A decision that goes in the direction of a fast rate adoption and large enough share. A decision that do not interfere with the technical implementation nor with the future improvements/developments nor with the possibility of having hackers-friendly options/customisations available within a reasonable range.
This brings us to please the 80% of our possible adopters and put the others 20% in condition of decide their own options and customisations. This is about product delivering, not about leadership, not about technology excellence, not about business nor money. It is about technology (SFOS) adoption and thus about technology (SFOS) success.
I hope to have clarifies enough my point of view. Therefore, I am attaching an updated list of tasks. Feel free to do whatever you like/want with this list.
