Btw, I do believe that bzr seems to be acting a lot like BK, at least when it comes to versioning. I suspect that is not entirely random either, and I suspect it's been a conscious effort to some degree. Which is fine, in the sense that there are certainly much worse things to try to copy. That said, at least BK was up-front about the versions changing, and didn't try to do anything to hinder it. It still confused some people, and it wasn't a great naming system, but it did work. In the big picture, the version naming between BK and git hasn't been an issue for anybody in practice, I suspect. So if you want to look at features that actually matter more, try out something like gitk drivers/scsi include/scsi on the kernel archive (I assume that somebody has tried importing the kernel git tree into bzr - quite frankly, if bzr cannot handle that size tree without problems, you have much bigger issues!). In other words, being able to look at history of more than a single file has been a _huge_ bonus. The other big difference is being able to do merges in seconds. The biggest cost of doing a big merge these days seems to literally be generating the diffstat of the changes at the end (which is purely a UI issue, but one that I find so important that I'll happily take the extra few seconds for that, even if it sometimes effectively doubles the overhead). Looking at the dates of the merges yesterday, they're literally half a minute apart, and that's not me _scripting_ them - that's me actually looking up the emails, typing in the "git pull " and pasting the source repository, and git fetching the data over the network and merging it, and checking out the result (and me verifying that the resulting diffstat matches what the email says). Doing four of those in a row in less than two minutes is actually a really big deal. At some point, "performance" is just more than a question of how fast things are, it becomes a big part of usability.
