I'd say one breakage at a time. :-)

I am fearing us breaking some ancient crap with it and Andy assures me
there shouldn't be anything except some ancient "pin" binary which has
been fixed in the meantime.

I'd say we can do the "none" by default thing but do it as a separate
patch so that it can be reverted easily in case someone screams in a
justified manner.
