Apps that haven't been ported to aarch64 (Store)

@slava Would you please humor me and explain once more? Because i’m obviously thick.
Hopefully we can pester the Store keepers (Harbour masters?) at another community meeting, but to do so effectively i need to understand.

I have SeaPrint built on latest build targets for all architectures, showing up and working just fine on down to and including 3.4.
3.3 and earlier get an old version, so no hiding going on that i could find. Are there some circumstances i’d need to hit for this to occur, or are you talking about new apps only?

My assumption is that the 3.4 cutoff is from gcc8 and library uplift rather than specifically aarch64.
Although obviously related, since no aarch64 target existed with the old compiler and libs, and if the system just takes the highest requirement for all the effect is the same.
Is this the core of the issue, or are there more things to it?
