Certainly.

Not necessarily.

This is the problem. Until there is a way to instantiate new-style
drivers from user-space, we just can't remove the deprecated drivers.
Even tagging it as deprecated is dishonest to some extent. So I see no
point in adding these drivers to the feature removal list for now. We
can do that later, when we really offer an alternative with the same
features.
You shouldn't fear that we forget to remove these drivers. They are the
dust in my eye, I can't forget them.

Good to know...

I'm confused now.
