Sure, I agree there.

It remains to be seen whether this is more or less sluggish than the jit-lock
version, because at least the naive jit-lock version is making lots of
requests over to the process.  In TRAMP scenarios or networking
scenarios, this may be slow.  So I'm am focusing on finding the best solution
but it's not immediately obvious that jit is always best, because of the fixed
overhead (in this case LSP comms), which doesn't exist in the use cases
jit-lock was designed for.
