And no real reason a program could not support 64ki-1 bytes. Not looking at the 
specs for "standard linkage" but there is no real good reason to treat the 
length as signed.

Beyond that would require a significant change in the linkage.

This is hardly such a novelty:  for a half-century the Assembler 
CALL/LINK/ATTACH macro could invoke the compiler with up to 32Ki-1 bytes in
