>You can't beat Hyrum's law by simply "forcing more people to use official API", with enough code people still depends on every implementation details in your code.
That's neither here, nor there though. You can still beat the biggest part of fragmentation by "forcing more people to use official API".
Doesn't have to be perfect, just good enough to make moving forward, porting to your new architectures and APIs, etc, easier.
In fact, Apple just showcased it works with the move to M1 (and to a lesser degree earlier with the move to x64 and the move to 64bits).
