I very much doubt Dmitry was replying to that 2-year old message.  He
was replying to what I said today.

What I'd like to see is a way to switch language-specific features in
CC Mode to LSP or some other similar facility.  Assuming that doing so
will make CC Mode faster and more accurate, that is.

If you (and/or someone else) can start working on that, please do, and
thanks in advance.  I presume that we are still a long way from that
goal, but if I'm mistaken, so much the better.
