we should either add addDefaultHelp or deprecate getDefaultName/Description to be consistent

The name and description static methods remain useful for lazy commands, but this approach is not necessary for help. Additionally, introducing a new getDefaultHelp() method seems redundant since it's already possible to override getHelp() when customization is needed.

would you prefer adding a private static method for getDefaultHelp() purely for the sake of consistency?

Are they really? I miss a case where it cannot be found in the tag and #[AsCommand]

Hmm, I think I missed the fact that the AsCommand attribute is always auto-configured, so yes! they can now be deprecated. I'll make the changes in another PR, as it's not directly related to the feature proposed here.
