And it's obviously inconsistent to delete and exists

That's what I've been saying. exists isn't consistent. That's why there's a warning. And you're right, delete isn't either. We've proved this so many times already!

keys is inconsistent to the behavior in hashes

Next you'll say that scalar(@a) and scalar(%h) are inconsistent!

Perl doesn't have sparse arrays. If $y[3] is in the array, so is $y[2].

keys returns the elements found the structure for both arrays and hashes. keys is consistent for both arrays and hashes.

Only exists and delete are inconsistent, as repeatedly demonstrated.
