I think that argument is wrong, actually.  Moving a function from a single
use-case into a library (with, clearly, the intention for it to have more
use-cases) is precisely the time when any weaknesses in its original
implementation might be exposed.  So extra scrutiny seems well warranted.

Whether the "extra scrutiny" involved in perlcritic's higher levels
is actually worth anything is a different debate, though, and so far
it's not looking like it's worth much :-(
