The counter has been global scope forever. If you want to encapsulate
it, send a patch yourself and make your case in the changelog. There
is no reason to make people with reasonable working code jump through
your personal preference hoops that have little to do with what their
patch is pursuing.
That being said, I'd NAK any patch that would turn a trivial accessor
like this into a full-blown function. Our interfaces encapsulate for
convenience, not out of distrust and bad faith.
