Technically speaking, vBulletin can have unlimited numbers of subforums and subforums its own subforums, but different thing is what owners want to do.
But, having prefixes in this case may be enough, with sticky main topics, as we already have.
I don't think that there's so much difference per platform that subforums would be advantage. Prefixes would handle that much more elegantly.
At the moment we are also lacking Koreader forum image, that I see Ken have attached in first post of this thread. Admins just need to be informed about it and put in its proper place, i.e. https://www2.mobileread.com/i/mr/misc/f-276.png Probably admins already know that, but it's still holidays season.
And as one suggestion, posts related with kobo H20, KSM and switching light on and off and shutting device off could be made into one thread, as this one little modification makes use of Koreader on H2O much easier, at least for me. Links to this posts:
