Nice, I like this new option, I've needed this functionnality before as
well. For instance I've seen dependencies like "prebuild-install" [0]
for which the whole purepose is to download binaries instead of building
them... in Guix we always want to remove those dependencies.

I'd suggest to add documentation for this new option in the manual, but
that could be done as a follow-up.
