This fixes eval for me. I’m building the stdenv now to confirm it still bootstraps.

anybody know if macfuse-stubs and fuse3 are similar enough to allow:

fuse3 = lowPrio (
    if stdenv.hostPlatform.isDarwin then macfuse-stubs.override { isFuse3 = true; } else fuse
  );

Not sure who would need to approve this move. @[Randy Eckenrode] ? https://github.com/NixOS/nixpkgs/pull/520945

Something planned out beforehand? Seems a little weird to migrate from an official repo to a new fork of your own with a handful of claude commits on a single day of dev with no real usage by anyone for a stdenv package.

xcbuild is abandoned and archived from Facebook's side

That makes more sense, then.

If you have any issues with the actually quality of the code I'll be happy to address it.

Nah, was just more concerned with the optics of the repo created/commits added/pr created to migrate on the same day just a few days ago for a foundational / widespread package.

I haven't been following it closely though so it was more of a question about what kind of problem solving / communication was done that warranted such a change.
