This simply Should Not happen. Guix's GC model (inherited from Nix) is
brutally simple: if the raw string /gnu/store/xxx occurs anywhere within a
protected /gnu/store/yyy (e.g. in a binary), then xxx is also protected,
recursively.
Assuming those assumptions hold here it's a 'mystery' why git got GC'd. From
experience and for our collective peace of mind I'd say it's more likely that
they didn't hold somehow, than that there's a serious GC bug :-)

So, no. Completely unrelated. The GC has no concept of time at all. This
isn't Gentoo.
Propagated inputs are 'oh, here's this extra thing I was unable to properly
patch, please add it to the profile and treat it as a GC reference anyway'.
This is ugly and regular, non-propagated inputs are always preferred. Some
software just makes them too painful.
Cees,
Kind regards,
