NTHCDR is not an accessor so (pop (nthcdr n list)) doesn't work. Both
POP and NTHCDR are for lists. DELETE-IF is for all sequences.
Those keyword arguments are not useless. Some of them are rarely needed
and that's why it's good that they are &key and not &optional.
I think
(replace-match "foo" :subexp 2)
is much more readable than
(replace-match "foo" nil nil nil 2)
