I think you'd be wrong here as personally i have used Git a lot more than CVS as i suspect would any developer nowadays who has at least a couple of years under their belt. And i think it is the exact opposite of what you are talking about that is happening: people already know Git and want to use it for everything - you see, after all, that the common response isn't something like "why would i use CVS again?", it is something like "why would i/some new developer learn CVS?", implying familiarity with Git and dislike towards learning a different tool.
