To be honest I think we should get rid of harmless messages - or only
show the first or last one (perhaps state that there are more similar
messages which can be seen in debug mode). I understand that this is a
guile thing, but the same holds for guix with all the warnings we get
when sylinks/files are duplicated in the store. 

Irony is that sometimes we don't get warnings when we need them. Such
as when you specify a substitute-url and if the server does not exist
there is no indication. I have wasted many a time on figuring that
problem out.

It would be nice to have a policy where we do not show all harmless
warnings by default, but only in debug mode, as well as missing
services etc. I am happy to run --debug when I actually face a
problem.

Pj.
