If you remove this behavior then it will be required that all subroutines be defined before ever being referred to.

Could you please substantiate this? I don't see why the autovivifying behaviour of \&foo is required to call functions not yet defined. In fact, the doesn't seem to be any such need currently. 

>perl -e"print exists(&foo)?1:0; exit; foo();"

It's perfectly fine behaviour for sub foo; to create a stub, but that's an unrelated matter.
