I guess I am a Luddite, because I have no interest in smartphones. It is not a big deal, but it would be nice to be able to select the two different categories, ‘Librem’ and ‘Phones (Librem 5)’, from the drop-down. The topics often do not seem to be related, and one would not have to wade through those in one to get to the other.
I acknowledge there might be many more who want to see both. The fact that they are already separate categories on the topics list leads me to think of narrowing searches, however.
