This sounds rather brittle: you need to keep things in your head. It’s
like being a liar: you need to remember what lie you told to what
person. And then you make an error and your byzantine construction (of
software versions or lies) falls down.

Is this in the spirit of Guix at all? I mean, is this functional package
management? Wouldn’t it be nicer to have manifests support an additional
(optional) field, viz. guix commit corresponding to given package, and
manage your profile using that explicit manifest file? Or aren’t
inferiors suitable for such purpose?
