True, but I'm not worried about files that intend to use the old
encoding at all. I just want to say

\input newmath
....
\bye

And have all of the glyphs & extensions available to me. Of
course, newmath.tex will have to redefine some of the stuff that
is in plain.tex, but that is a trivial exercise in comparison.

Copying the whole nfss2 into plain.tex is not what I'm after, but if
you want to use \decimalsep or whatever, somewhere along the line
there has to have been a \mathchardef for it.

Actually, context still lacks a real, full-blown math interface like
amslatex. Since it is fairly simple to separate the \mathchardefs
from the user interface, this is what I will do, resulting in a couple
of separate files:

newmath.tex   -- generic macros and \chardefs
nmnames.tex   -- font tfm specs file for plain
font-nm.tex   -- font tfm specs file for context
supp-mat.tex  -- user interface for context

As I intended.
