I'm for it.

Note that we will need to do a *bunch* of education around the change in
version numbering schemes.  And a bunch of people and packagers will
need to change their version comparison scripts (while everyone should
be using the sortable version numbers, not everyone does).

So if we're going to make that change, I suggest doing it *now* to get
the word out.
