I'm still not convinced about it being an option I want to offer, because people use tags for lots of reasons other than just genre
Where's the problem? You have to map tags->shelves anyway - so if you have a tag for which you don't want a shelf to be created, you just don't map it.
And the other thing that you're still missing is that "Shelf" (in goodreads) has nothing
(explicitly) to do with genre. In Goodreads, they are
tags. I don't want all of my tags to be set in my e-reader as Shelves (as can be done with the Kobo driver) but I pretty much want all of my Calibre tags to be Goodreads shelves - but again, if you don't, you just don't map them.
