> The next level is allowing an app to check its own package for modifications

You can't modify them. They're signed. If you modify and resign it gets installed with a different key (ie the one you signed with) hence it's a different app as far as it's concerned.

To get around that you need signature spoofing which Lineage famously refused to include.

Agreed that BigTech in general is making the world worse by implementing security features in ways that erode user freedom.
