Indeed.  My understanding of the proposal is to split some checkers (as
derivation) and then group them to have the expected behaviour.  You
wrote [1]:

        I meant that it’s important to have a single ‘derivation’
        checker that checks derivations for all the supported systems.
        Packagers should be able to run ‘guix lint -c derivation PKG’
        and be confident that it’s fine for all systems.

and Chris answered [2]:

        I think we can still keep that by adding support for grouping
        lint checkers. So have a derivation group, instead of a single
        checker.

        Maybe that'll change the command slightly to 'guix lint -g derivation
        PKG', but I think that can be equivalent.

where I try to feed Chris’s proposal. :-)

I do not know if it is the correct level but being able to run “smaller“
checkers appears to me worth to try.
