What do you think if we were to add  a smart user message to the `guix refresh
--list-dependent ...` command?

I was thinking something along these lines:

```
$ guix refresh --list-dependent ruby-parser

Building the following 1991 packages would ensure 5378 dependent packages are 
rebuilt: ...

ruby-parser reported 5000+ packages. According to Submitting Patches section of
the manual, above 1800, it should go to core-updates (at the moment).
```

Like that, the command reminds the user/calculates for the user what
branch to put the package in.

I'm imagining it would be as easy as just getting the length of the output and
matching against it the appropriate message?
