Yes, and I always found it awful.
Which of the 10000 functions of the base and recommended (and other CRAN ?)
packages should be highlighted and which not?
Also,  "{" and "(" and "+" and .... are all functions as well in R.
Honestly I've always found it distracting and a bit ridiculous when
I've occasionally seen other  editors do it....

but yes, it is a entirely a matter of taste (and what you are used to).

I think we should make this easily configurable, in a similar way that
"C-c ." allows to set the ESS indentation style, there should be a
simple way to choose
one of a few predefined fontification schemes  (and then, of course,
the user is free to choose her/his own colors for the
font-lock-<foo>-face
((in emacs: menu [Edit]
                      --> (at bottom)  [Text Properties]
                          --> (almost bottom)  [Display Faces]
))
