Thank you for this explanation. I fighted a lot with the concept of
propagated inputs and this descriptions makes a lot of sense to me.

I am progressively thinking that propagated-input are used too much
in Guix packages. Python packages seem concerned a lot by this but I
have not used Guix enough to know if it is localized there or if it
is generalized. At least it is a risk I am just identifying on the
way Go packages are done (and makes me think about how we can evolve
go-build-system to avoid this).

I am not sure about what to do with that but reading this makes me feel
less alone.
