FWIW shrinkray gets to 162 bytes if I leave it to run for about 10 minutes. https://gist.github.com/DRMacIver/ee025c90b4867125b382a13aaa...

I think it might do a little but not a lot better if I left it to run for longer but it looked to have mostly stalled then so I got bored and killed it.

I actually tried to Shrinkray it myself, but after ~3 minutes it crashed with the following stack trace:

      (4 nested BaseExceptionGroup: Exceptions from Trio nursery (1 sub-exception), and then:

Not sure if this is a known issue? Note that I ended up not respecting all of the version requirements in the pyproject.toml since I tried to run it all in Nix and there the Poetry support is currently quite lacking.

Interesting. I've not seen that before. My best guess is that it might be an old trio version or something, but I'm not sure.
