What is wrong with them?

We have them in Elisp as well, `cl-remove-if' and
`cl-remove-if-not', both in cl-seq.el.

Those functions are pretty useful IMO including use which
includes the keywords, all tho that is optional.

The only thing negative is the documentation, see for example
the docstring of `cl-remove-if-not':

  Remove all items not satisfying PREDICATE in SEQ.
  This is a non-destructive function; it makes a copy of SEQ
  if necessary to avoid corrupting the original SEQ.

  Keywords supported:  :key :count :start :end :from-end

As you see, it only says what keywords are "supported", not
what they express or how they effect the execution of
the function.
