Things like this combined with the countless ways to hide "feature flags" in a giant codebase makes me feel that anything less than "the entire app was verified + there is literally no way to dynamically load code from remote (so even no in app browser) + we checked 5 years of old versions and plan to do this for the next 5 years of update" is particularly meaningful.

Still very important but my issue has never been with zucks inability to produce solid software, rather in its intentions and so them being good engineers just makes them better at hiding bad stuff.
