As I've mentioned in another reply on this subject, decoupling cc-mode
releases from Emacs-releases will make it harder for third-party major-
modes deriving from cc-mode to maintain compatibility when cc-mode
introduces breaking changes.
Currently we can inspect "cc-mode version" by checking emacs-version,
and dispatching compatible code based on that.
Checking version numbers is the wrong approach for feature detection,
and should only be a last resort if checking behaviour is not practical.
If an ELPA package results in more frequent updates to cc-mode then
third party extension authors will simply have to adapt to a slightly
faster release cadence.
