While I indeed see the move, I get an error evaluating it:

Would you like to create an upstream issue?

@raboof are you sure it isn't a problem with flake-info?

i'm not using microvm-nix personally but i tried to understand the issue;
it might be because the flake need to be called with an argument / the desired output

nix flake show github:microvm-nix/microvm.nix seems to take ages to complete

@raboof are you sure it isn't a problem with flake-info?

it's very possible that this is a problem with flake-info, but I don't think anyone is actively developing flake-info at this point, so if it can't process a flake and someone would like it to be in the search (which it looks like they would), I think it's reasonable to ask them to help look into this.

[Malix-Labs]

@raboof what is missing from nix flake metadata / nix flake show to not being able to replace flake-info?

[raboof]

I don't know, would indeed be interesting to compare

[Malix-Labs]

See #1117

[Malix-Labs]

The problem is most probably not from flake-info
