Are skeletons worth it?

[Maya]

is awful against Celestials, and I don’t know how you can even attempt to fight them with something as squishy as Skeletons

Very patiently

I think Skeletons are the least lazy pets to play. You have to be physically involved to keep them alive and often even that will not help, cause they break down faster than you can summon them. And that leads to shouting"Nooo" more than Darth Vader.

Actually they can be one of the laziest
This still works: Skulls & Bones - Pet Cabalist

But the issue is that, unlike say in a Briarthorn or Familiar build where you can achieve that sort of laziness without much sacrifice, here, it takes ages to kill anything.

Though do note that Crucible is a major pain to attempt it with Skeletons. Especially after the aggro change.
