Please allow me to jump in and voice my opinion here. To me it doesn't
make sense to concern the Guix client with implementation details of how
the caching of substitutes happen and its impacts.
This situation is bound to change in the future or become irrelevant
(say, if a new build farm would be able to sustain higher transfer
speeds to the cache mirror), or if the caching implementation changes.
If the current cache building implementation is slow to the point of
being a problem it should be fixed (or documented).
Cheers,
Maxim
