Indeed. As much as I would like to use Ruby or Raku for this type of stuff, I keep coming back to Perl because it's simply... there.
Sure, I could probably install Ruby on any machine I want it, but it's not just technical availability. Socially, Perl serves as a quite obvious Schelling point. I don't have to convince four other people to learn Ruby, because Perl is what everyone would gravitate to even in isolation, again because it's just... there.
(That said in recent years I've had to switch to Python for some things aimed at a younger audience. Oh well.)
