If falling out of fashion is that good reason then yeah. At least it's not a highbrow esoteric language thingy that next to no-one in the wild used to begin with.

I've personally fixed an early noughties Perl script where one of the modules it used had changed its name (but thankfully not the interface, not significantly at least), among a couple of other compat problems. Fixing it turned out pretty straightforward even for someone who's far from a greybeard Perl "hacker".
