Thanks. I think we need not to worry the user address space too much.
Those functions are descriptive so it is unlikely someone wants to name
a function say remove-if that does something different. Even if they do
they can still play with the name by adding *, +, ++, x etc as we have
seen in many places. The majority can continue to like what remove-if
does.

But all the major build blocks like define-derived-mode, defcustom,
define-minor-mode, easy-menu-define etc use keyword arguments.

And completing-read, I often want to specify the DEF argument and it is
pretty difficult to remember where it is without checking it out with
C-h f.
