IIRC, the original definitions are from plain.tex and amstex.tex.
plain.tex says:
\def\joinrel{\mathrel{\mkern-3mu}}
So I guess that \joinrel indeed needs to be defined on per-font basis
instead of being hardcoded into definitions.
the macro \loadfontgoodies in font-gds.mkiv should be extended
to something like
\def\loadfontgoodies[#1]%
{\ctxlua{fonts.goodies.get("#1")}%
\InputIfExists #1.tex%
}
which already load a lucida-math.ldf (lua code)
and then an optional lucida-math.tex (tex code)
don't know how ConTeXt can handle the \InputIfExists
The file lucida-math.tex in /context/fonts/
gets all font specific redefinitions, in this case
\def\joinrel{\mkern-4mu}
\def\longrightarrow{\relbar\joinrel\rightarrow}
\def\longleftarrow{\leftarrow\joinrel\relbar}
....
sich files are then possible for all other fonts
in mkii we had math vectors and one could have many different vectors
active at the same time (so, lucida alongside lm and others); in mkiv we
assume unicode math
I can probably make something for mkiv but the question is: is it worth
the trouble and complication. Eventually all these math fonts will be
open type anyway.
