Comment 3 for bug 1927149

That's true. My thought was that there is typically no reason to include appstream in Build-Depends.

I don't know the reason why appstream and gettext ship different versions of metainfo.its. Possibly there are cases where the appstream version makes more sense. If there aren't, it may be motivated to turn to appstream upstream and suggest that they adapt to the gettext variant also in the appstream package.
