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 lucida-math.lfg there is now: variables = { joinrelfactor = 4, -- default is 3 } and when set that variable will be used in composing the virtual glyph (the default is 3). So, no complex defs are needed. Maybe there are more relevant variables.
