I agree that it's not a bug, but perhaps it's more like a wishlist item.

Ideally, users would not need to concern themselves with implementation
details like protocol selection.

Guix could offer a more unified or simpler interface for authorizing and
selecting substitute servers, and it would handle server addresses,
communication protocols, and key authorization. Currently it's very
ad-hoc.
