Off course, I understand that is annoying that a certain question keeps popping up.
In my defense, I did my share of searching but perhaps not thorough enough.
A search with ´bluetooth android´ did not come up with much usefull for me.
I just did a search with ´bluetooth - android app support´ and that was a much bigger hit; there were some threads which could helped me from raising the question.
On the other hand…
I fell for AAS reading this: AppSupport - Jolla and the whitepaper
No mentioning of a list with known issues at all.
I guess that a lot of people do as I do, reading of a huge compatibility rate and lots of functionality that works out of the box (some do, others not like VPN apps ). With such a hallelujah-story there is no direct need to search on fora for know issues. And as you said, the issue with Bluetooth only recently was added so I wouldn´t have know it last year.
For me, it remains quite an issue.
I asked tht developers of Briar if they are familiar with the problem.
That was before I read your comment that it perhaps is technically impossible :-/
But as I learned from Th Lord of the Rings: there is always hop 
And than again, afterall SFOS + AAS is great alternative for phone OS´ses and I´m happy testing it further.
Thanks for your answer and again apologies for any unment annoyances.
