I could try that, but mupdf is a pretty heavy dependency. guix size says
it's self-size is 208MiB and total-size is 491MiB.
I personally never needed it with mcomix, so I like that it is optional.
Is there some way to define a package with optional inputs?

For now I'm appending my WIP that should address your previous remarks.
