The <mchar> tag simply provides a mapping to existing
characters (or Unicode points). It doesn't cater for new 
symbols. I guess you are looking for <mglyph>. This one is
going to be a really useful tag for new symbols, if it is used
correctly, and if font designers play by the rules (otherwise
we may run into problems like with TeX fonts which have
different encoding indices depending on the platform).

There is more to this than just CPU. Deprecating entities means
they are going to be obsoleted/removed in the next versions.
So some of us want to understand the issues and appreciate
the explanations of the thoughts that are going on in the WG.
