I found the reason, it's because of this:
https://github.com/NixOS/flake-registry?tab=readme-ov-file#flake-inputs

Looks like it's available for every nix flake users officially and one can implicitly turn it off by configuring the registry options I guess.

But it's suggested to add inputs explicitly, since u might change ur registry later in ur configs in future.

Unexpected learning🤝
Thanks for pointing out this
