I don't want to block new drivers unconditionally but at least I want
to know which direction we're headed in the longer term.  Right now it
feels like we could be at the beginning of an uncoordinated explosion
of these drivers which will take a hell lot mpore effort to clean up
after the fact.  I could be wrong and these could actually be
different enough to justify separate drivers and there isn't gonna be
an avalanche of these but again I at least want to know the general
direction things are headed before making any decisions.

Thanks.
