If there's an implementation that's deemed superior to what's there now,
then 3.0 is exactly the right time to break 3rd party extensions. Of
course 3.0 isn't a blank check for gratuitous breakage, but being
conservative *solely* for the purpose of not breaking compatibility
defeats the purpose of having a 3.0 separate from the 2.x series, IMO.
