I consider a linker that disallows certain code for no good reason
broken.  If the code works on x86-64 running Linux, there is no reason
not to allow it in MacOS.

Besides, the code *is* PIC in the sense that it has no text
relocations.  What is your definition of PIC?

"Improperly written" according to whom?  If it runs and does the right
thing, it is IMO properly written.

Fine by me, so long as you don't report bugs against that version.
