I'm genuinely not sure since I haven't touched the tablegen stuff in ages, but is it possible to use `foreach` to define multiple `TaggedEtor`s instead of defining this new templated etor type? It would simplify our tablegen backends a bit not having to loop over the template values in a few places.

Not a big deal to me though, just a thought in case you want to look into it.
