Oh, I apologise — I’m still using the TL2015 version of LuaTeX and hadn’t caught this news. The \Uhextensible primitive is exactly what I was thinking of (and the other new maths primitives look good as well — thanks!). Whether \Uvextensible is really necessary is an open question — I’d say that it’d be "good to have” but doesn’t solve as much of a need as the h version. > (It is unlikely that the math engine will be touched much, at least nto > before 0.95.
