I think we agree.  Except that for me, it should also not try if it
cannot do it quickly enough, not only reliably enough.

I was talking about what to do (or not to do) with our existing
regexp- and "syntax"-based fontifications.  I still remember the days
when CC Mode handled that well enough without being a snail it
frequently is now, and that was on a machine about 10 times slower
than the one I use nowadays.  The C language didn't change too much
since then, at least not the flavor I frequently edit.
