I agree with that.

There is maybe a middle ground in this -next idea; 
as very first part of the series, the new api gets added, current users converted
and api marked __deprecated.

Then there's a second part to the patch, which is a separate tree, which gets
added at the very end, which removed the old api.

Both will go in at the same merge window, and the next-meister needs to track that
no new users show up... but the final tree allows this to be done somewhat more gentle.

Doesn't work for API changes that just change the API rather than extending it, and
doesn't solve the dependency issues. So I still think a cleansweep works best in general,
but I suspect Andrew just disagrees with that.
