Not a problem for me, one or the other is not bad, just a different
style. (I prefer the common-lisp style for `if')

I understand your point of view, the problem is to indent and fontlock
correctly all the common-lisp style functions used in emacs-lisp-mode,
in one way or the other.
I agree that the best would be to handle this for emacs-lisp-mode
without using an indentation destinated for another mode (lisp).
Unfortunately it is missing, not implemented, so we use the "less bad"
solution, using common-lisp indentation style for all with some tweaking
for the cl-* ones that are not supported in both style.
