>That said shipping JIT / interpreter with your program to recompile updates / parts of it sounds silly to me.

why is it silly? modern phones can easily do this (they are running local llm, what issue is with jit?), if it's done one time per update what's the problem?

what's the problem with jitting couple of hot paths which have been updated and were not part of base app?

>Apple does not allow running code from internet either (even if interpreted iirc)

And how is React native expo/eas updates are working then? Isn't it downloading a bytecode bundle?

Afaik, interpreter is allowed. JIT isn't?
