TBH, I don't see a real difference either.  Stefan says that "this way 
it's easy to later refine the mechanism", I guess because it is possible 
to "refine the mechanism" without recompiling Emacs.  But as I said the 
problem is that there are other users of fontification-functions besides 
jit-lock-function.

Could you (or Stefan) please have a look at the bytecomp.el problem I 
mentioned at the end of my previous post?
