...Then you write `os_lock_screen()`, and THEN
you write `PERMISSION_LOCK_SCREEN`, then
years later you make an API for hooks into
the lock screen mechanism, and suddenly
your permissions there need "levels",
so you write a permissions system
that has an entire new set of
permissions with levels, but
someone put their fancy
new threading model
into it, which causes
misses for certain
permission-check
failures on the
app's side, so
developers,
annoyed,
*leave.*
