I think that's debatable. Mozilla was terrible for a long time, there just wasn't much alternative. You could make the (arguable) point that Mozilla's rewrite happened at the cost of disengaging from the web community, leading people to jump ship to IE.

I don't think Apache is a particularly good example of why ground-up rewrites are more reasonable in open source projects. It took **years** to get a critical mass on Apache 2, and there are still many plugins that don't support anything but prefork mode.
At the same time, the approach to developing the 1.0 series was the source of the name Apache, since they were constantly upgrading and improving an existing codebase, hence, "A Patchy" Server.

Well, again, debatable. OpenBSD still uses CVS, and has started a significant push to patch and upgrade the existing CVS source.

I think it's far simpler than that. There's an old expression that sums it up: A bird in the hand is worth two in the bush.
Taking limited resources from a nearly-complete and reasonably popular project to add them to a brand-new and **backwards-incompatible** project is rarely ever a wise project management decision.
