But you don't see anything when you are selecting the drivers and that
is the point. You now can't select this separately. There is now no
option for it.

Why should we bother the user with this? The user is most likely only
interested in the drivers and by selecting those the user will get the
interface. The drivers will need to have the dependency to the class
set correctly in any case.
