cc-mode is not only used inside core Emacs, but also by third party
developers.
cc-mode has historically been shipped as part of Emacs, and has (as I've
understood things) tried to maintain a compatibility situation in line
with that: i.e. a minor Emacs release should not warrant breaking
changes in cc-mode.
When cc-mode has breaking changes, third-party major-modes deriving from
cc-mode trying to provide a reasonable level of compatibilty (thus
reducing friction for end-users), has previously had the option to check
against the running version of Emacs to decide which code-path to use.
As such, a change like this seems to impact third-party major-modes
deriving from cc-mode.
I'm not saying such a change universally and categorically will make
things worse (I can see some things improving too), but I think it
makes sense to consider the full impact of such changes before
committing to them.
