I said these are things I've raised with the rest of the team: at
present discussion has gone no further than that. Adding stuff to the
kernel is a tricky subject, but the team note that in reality
LaTeX-based formats for both XeTeX and LuaTeX already do various things
that are not in the kernel code (see the relevant .ini files).
