Describe the bug

We tried updating hydra.nixos.org to Nix 2.20.1 today, and it started failing to build remotely when talking to builders running Nix 2.13.3.

I suspect the cause is related to some protocol stability breakage, but I don't have any evidence to prove it, and I don't have a good setup to test this. Filing this bug so hopefully someone with a better testing setup can have a look, or maybe someone even knows what might have changed that could have caused this.

Steps To Reproduce

Try to remote build from Nix 2.20.1 to a builder running Nix 2.13.3.

Expected behavior

Remote build works.

nix-env --version output

2.20.1
