Right. Sure.  We believe you.  Fer shure.

You have proven over time to not understand what your eyes and ears are 
sensing.

Uhm.  No.  It's translating the call frame as well as the callee frame 
be necessity.   And a convention for the one dictates the convention for 
the other.  Thus translating the one, dictates the translation of the other.

As I've pointed out to you, translation does not have to be primitive.

The translator is translating both the call and the called, so no issue 
in matching that up (primitively or smartly).

Call conventions between an intel machine and an ARM machine are not 
especially different for a given language - and where they are, 
replacing the one with the other is not especially difficult.

And finally (again), the ARM offers 13 more 64 bit registers than 
_x86_64 ... providing ample opportunity to improve call/called related 
operations.

But, no, you seem to believe that Apple would do a primitive job in 
Rosetta 2 to back up billions in RD&E on the Mx.
