So far, the performance didn't improve significantly.  Either there are
other changes that did make editing C deteriorate considerably over the
past two years or I still have to tweak some internal settings.  I'll
get back to you as soon as I know more.

Funnily, a few minutes ago I read that for performance reasons an
implementation of "parinfer-mode"
(https://github.com/oakmac/atom-parinfer) relies on a similar feature.

We still also should fix the font-lock issue you reported elsewhere.  I
have no idea yet why it doesn't work any more.
