@DavidCarlisle Oh, now that I look quickly my initial guess was right after all; I got the details muddled in the early morning fog. LuaTeX doesn't kern catcode-letters, so we turn all letters into others. And there's no point having @ specially defined in maths, so I'll just remove it from the table.

@DavidCarlisle How about if I just remove the optional argument from unicode-math?
