Yes, but that’s OK to me: IMO, procedures have to focused on one thing;
users can perform additional processing beforehand if they need it.

Conversely, commands have to do the right thing by default, which is why
I agree that ‘guix download’ should rename automatically when needed.

How does that sound?
