This is one of my issue with the PvP. with the PvP versioning you're not
able to convey any other informations apart from the API "changing".
Which means you can't properly convey:
* major new features: by bumping the major, despite the API not changing
* security (by bumping the minor or patchlevel, regardless if the API
* the stability (bumping to 1.x).
Text is one of canonical example when it was bumped to 1.x recently and
lots of people complained that it wasn't the right thing to do.
