I don't mean to agree with people who resist this type of change, just to explain how it looks from their point of view. A CVS user sees branching and merging as a difficult, painful, time-consuming things to be avoided, so they're horrified if you tell them they're going to be branching and merging on a daily basis. They aren't right — generalizing from their CVS experience has given them a mistaken idea of what using git (or fossil) is like — but it's easy to understand why they're afraid. Also, ironically and unfortunately, the fact that a git (or fossil) advocate is enthusiastic about the ease of branching and merging is likely to make the CVS user think they are crazy, since you'd have to be crazy to love branching and merging in CVS.
