Is nosys incompatible with flake-compat

Help
1

I have a flake in which I am considering replacing flake-utils with nosys.

After switching to nosys, the flake-compat-based shell.nix no longer works (when shell-nix is invoked).

Poking around the nosys repo, I see that at some stage flake-compat was replaced with call-flake with which I am unfamiliar. Further digging leads to more questions than answers, so I hope someone kind soul might be able to tell me …

  • Is nosys simply incompatible with flake-compat?
  • Is there a way of providing a legacy shell.nix which delegates to a devShell in a nosys-based flake.nix?
