Hi Ricardo,
I tried it. It provides interesting statistics, but always considers all packages in Guix rather than just the ones I care about.You can pass a manifest to “guix weather”.
Found it in the manual - great! And a quick look at the source shows that it shouldn't be too hard to make it print a list of the packages that are not available as substitutes. It's on my to-do list...
Thanks, Konrad.
