Apologies for the slow reply, it's great that you're interested!

I think there's a general discrepancy between how Guix works and how
mirror sites generally work, but there are probably ways of bridging
that gap. Maybe all the nars for the latest release could be mirrored
for example, and the nar-herder could probably help with that.

I think setting up some mirrors closer to the people that use Guix is
now easier to do with the help of the nar-herder.

Indeed, and this is something to strive for in the design.
