Right, we don't want to stand in the way of people with more powerful
hardware and more bandwidth. This is a concern I brought up the last
time we had this discussion. [0] The limitations of our current hardware
should probably not be baked into the Guix codebase.

On the other hand, I think that for each user that comes to IRC or
help-guix to ask about this, there are several more that give up or
(hopefully without too much frustration) figure it out. It's a bad user
experience.

I think that the current error message is clear that the solution is to
try again with --fallback. I think that if people won't read this error
message, they probably won't read a longer error message. Although
perhaps the list format will catch their eye.
