I'd be wary of changing the behavior of return values, as it seems like the sort of thing that someone would write code expecting one behavior on a 'user friendly' version, and then be surprised when their code broke horribly when using a 'full' version of Perl.

Not quite a perl example, but I worked at my university's computer support center during my undergrad. The engineering school had aliased 'rm' to 'rm -i' on all of the boxes they maintained ... someone had an account on one of our 'normal' systems, and to clean up their directory typed 'rm *', expecting it to behave like 'rm -i *'. Needless to say, they were not happy to have lost the training wheels, as our policy on backups was for catastrophic recovery, not as an 'undelete'.
