If the purpose here is to facilitate mutating anything in the store,
then we cannot accept this.  The entire design is Guix is based on store
items being immutable, and we assume this throughout the code, most
notably by assuming that store items and parts of store items can be
aliased instead of copied.

If you want to add something to your profile, e.g. fonts.dir, then use
profile hooks for that.  See %default-profile-hooks in
guix/profiles.scm.  However, we already have a hook to build fonts.dir,
so I'm not sure what's missing here.

If we've misunderstood the rationale for this patch, can you help us
understand what you're trying to do?
