But this requires a whole typescript. So there is no way to say
something equivalent to
\font\a=Asana-Math.otf \a
without the need to create a lfg file & so on?
Anyway, your example with Asana broke a compilation, so at least I was
able to realize that I was missing the otf font, whereas yesterday it
was simply ignoring the fact that the font was missing and has typeset
everything in TeX Gyre I think.

And how do I know what is an equivalent of StylisticSet=4 in Lucida?
Would this be something like
italic = { feature = 'ss01', value = 1, comment = "Mathematical
Alternative Italic" },
where \mathalternate{italic} works as +ss01, but the ss04 not because
it has not been defined in lucida-opentype-math.lfg?
