This patch will NOT prevent development of multiproto! DVB-S2 is here to stay and it is only being developed for multiproto. As well I've heard the kernel maintainers want multiproto asap. In the meantime there are some drivers which exist in v4l that people still need. I personally have a mixture of cards. Some need v4l, some need multiproto, some can use either tree. I appreciate the wrapper as I've been told directly that some drivers will not be updated for multiproto until multiproto is fully adopted!
