Would any part of this be feasible to port to another OS?

[Mr. Beedell, Roke Julian Lockhart (RJLB)]

Although cross-platform GUI toolkits exist, I presume that it doesn't utilise one, and the underlying work is Camera2-specific. Would any part of the work put into Open Camera be usable when constructing a similar application for a GlibC-based (rather than AOSP's Bionic) OS, like postmarketOS? I ask because I'd like to not be forced to operate WayDroid (or the deprecated Windows Subsystem for Android) merely to be able to utilise the features of my camera.

I've tried asking for recommendations for alternative camera clients at community.spiceworks.com/t/1226828, but all I've realised is that I might need to accomplish this myself, since Open Camera is unparalleled.
