Unlikely, but possible. I have used Counters as global variables is the past because, well they are there and I didn't need them for anything else. I have at least once used a counter as a timer of sorts that incremented every frame and expected it to wrap and keep going. We are talking about fixing a non-issue and creating potential issues for any scripts in the last ~10 years that expect a variable to act like a variable.
I'll ask this plainly this time. Why is the way it is now an issue?
