Yeah, but it's deprecated, and - as I understand it - may be removed
completely in future versions. Also, in the future, if you are working
with code from another developer, it's likely that developer will use
the new format. I suppose you can use both - but what an awful mess
that would be.

It seems to me that 3.0 is changing a lot of non-problems. And it's
going to be slower to boot.
