The Linux part was never a problem. The userspace is.
For the proper opensource apps, this can be fixed by the package maintainers (shout-out to the real heroes!).
For proprietary, compile-once run anywhere apps, that was always a problem. For more info, I recommend this great FOSDEM talk by Simon McVittie from Collabora.
There was always a need for a specific system dependency like for the file picker. There was no universal API that uses a system provided way to have a file picker. It had to be hacked together by adding dependencies to the app and everything that comes with this
Uhmm… It was always possible to make an “app” that works on all linuxes the same.
