Flight software is fabulously expensive to maintain and update, because it is safety critical. Furthermore, avionics programmers have a surprisingly captive audience. You would be surprised to learn how many problems are left to operator-based workarounds.

It's actually fairly depressing and is part of the reason I transitioned to consumer software.

This! One way to mitigate safety critical issues is to pass it onto humans. This lowers how detailed you have to be when verifying the software, because you don't have to handle some critical aspects.
