s/revids/revnos/g  but yes, I think I said this later in my previous
email.

So revnos aren't globally meaningful in fully distributed settings. So
what? I don't see how this translates into bias. There is a lot of
functionality provided by bazaar that doesn't really apply to my use
case, but it doesn't mean that it is indicative of some bias in bazaar.

I think you've switched revids and revnos, but I get what you are
saying. In fact, I think I said pretty much the same thing in the email
you are replying to. I don't think that anyone is disagreeing about
anything other than the assertion that bzr is biased because revnos are
used to simplify cases where it is possible to do so.

In any case, Matthew Fuller & Carl Worth cover this in greater detail in
emails further down in this thread (or one of its siblings), so I think
I'll stop here.
