Wouldn't taking the functional/reproducibility aspect one step further 
migitate this issue? I.e. maintainers of decentralized repos just need 
to have as input the precise guix version they are using?

For me using guix as a function to produce a piece of software just 
gains another argument: the guix version. If ignoring all the gory 
details and forgiving my ignorance is

guix-build: guix-version -> package-spec (+closure) -> binaries

applied to a particular guix-version gives

guix-build(guix-version): package (+closure) -> binaries

(It's "just" currying)

This of course introduces the problem of possibly having separate guix 
versions on a single system, possibly sharing a store, but it's an 
entertaining thought nonetheless, no?
