What about two or more packages?  “guix weather foo bar” when the
package ’foo’ is available on one server and ’bar’ is not at all.  Or if
’foo’ is available on one server and ’bar’ on the other.  Etc.

We could have:

 0 100% all servers
 1 100% from one server
 2 100% from a server mix
 3 one or more substitute is missing

WDYT?
