Fontspec was just an example, but I do get the same "mind blow" whenever
I attempt to read any TeX code of moderate complexity, and I'm pretty
sure it isn't only me.

If there is a working TeX implementation, then it is fine, but FWIU,
microtype for LuaTeX can only do protrusion/expansion so it doesn't
provide much more than what luaotfload does provide now (except that we
don't have many predefined sets, but it is easy to convert microtype's
to some lua tables), so we are mostly talking about unwritten code here.
