The documentation gives me the impression that it should work without
substitutes, when I have the package installed.

I think guix size should automatically search for the grafted version,
unless there is a technical reason/another use-case for guix size that
I'm not aware of, for which it makes more sense to use the ungrafted
version.

If that's the case, maybe say that in the documentation?
