While I do think modules.homeManager is preferable, this isn't wrong.

See this issue, though I disagree about configurations.<class>

• Replace 'configurationsXyz' and 'modulesXyz' with 'configurations.xyz' and 'modules.xyz' #6257

Do we need homeModule? Wouldn't it be better to standardize on homeModules.default?

I feel this had to add homeManagerModule + homeManagerModules too.
2k use case is not a small amount considering homeModules + homeModules only use 0.3k.

I checked all of resources that I can find but the only thing I found was @shajra's one comment and they are not even code contributor. I think considering how many people actually uses homeManagerModules more than this one is more important as Known but unchecked community attribute

I switched from homeManagerModules to homeModules and like that it's shorter. I think it fits well for merging home-manager into nixpkgs since it's similar to nixosModules.
