I'm expecting that when I flip that switch, a bunch of people will show up to complain. In particular, I think many downstream packaging systems (Linux distros, Spack, etc.) are...

Flit 3.4 will have a `--setup-py` option, and a message saying that the default is going to change.

Whew. There's quite a lot written here before I read any of it, so apologies if I've missed some of it. It seems that the motivation for this request is...
