Just merged it - Go, Helm, and Python have the bulk of the remaining backend Gets - the rest are kinda just scattered around as union rules mostly

question about the unions: should I just leave them unmigrated in my prs? Is it ok to intermix Get and call-by-name in the same function?

Yeah, mixing them is fine - we've just been leaving union rules as we don't have a migration plan for it yet. There is no harm in having both call styles, as they're well supported

Helm should be done soon. I pushed a commit to avoid the main rule cycle.

I might be able to - I just noticed adhoc wasn't listed anywhere, so trying to land that

apparently there is also a src/python/pants/backend/codegen/soap/java but it is not hooked up with a register.py
