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. François
