Indeed, I see no particular preason to have it as a propagated input.
The v2 attached below implements your suggestion of making it an input
and patching gnus-harvest.el to use it.

Summarizing our short chat in #guix, I'm a bit torn on this.  I would
personally probably add message-x to my profile whenever I wanted to use
gnus-harvest, but I'm not sure if I'd want to impose that onto others.
Especially since message-x, like bbdb, is an optional dependency and is
mentioned in the package description.  Of course, if it turns out that
people really always want message-x automatically pulled in along with
gnus-harvest, we could then add it as a propagated input.
