This is exacly providing this very feature.  You use it like this:

    guix weather --substitute-urls="…" -m my-manifest.scm

and it tells you what the current substitute coverage for your manifest
is for all substitute servers you interrogated.  (It does not give you a
total percentage when all servers are considered, unfortunately.)
