postmarketOS

Hey everyone! I recently decided to try mobile linux on an old Pocophone F1 I had lying around and installed Ubuntu Touch, Postmarket OS with KDE and Phosh on it (in that order).

I couldn't help but notice that while UT and Phosh had their own app stores (openstore and gnome software respectively), the KDE mobile's Discover had very little in it.

So my question is - is it possible to install either the UT's openstore or Phosh's software store on a KDE install of Postmarket?

I feel like this segmentation of app stores is really hurting the mobile linux ecosystem, since we have very few apps anyway. If we want more developers to make native apps for this platform, we should have some kind of standard packaging format that works on all mobile linux platforms (the same problem exists on desktop linux to a degree btw). Is there a solution for this conundrum?
