Why do you continue to repeat this argument?  No one is claiming that
a revision number by itself, as Bazaar uses them, is a global
identifier.  In fact, we keep on saying that they only have meaning in
the context of a branch.

And, unlike git, Bazaar branches are all independent entities[1], and
they each have a URL.

So:

http://code.aaronbentley.com/bzrrepo/bzr.ab 1695

is a name for

abentley@panoramicfeedback.com-20060927202832-9795d0528e311e31

And it does not depend on any other branch, especially not bzr.dev

Since:
1. anyone with write access to the urls can create them
2. anyone with read access to the urls can read them
3. the maintainers of the mainline have no control over them
   (except as provided by 1)

these identifiers are not centralized.

If you don't use centralized numbers (i.e. always refering to bzr.dev,
either by using always (bzr.dev URL, revno), or by using "merge" for
bzr.dev and "pull" for rest), the numbers are volatile. If URL vanishes,
then (URL, revno) to revid mapping is no longer valid. Yeah, I know,
cool URI don't change...

Besides, you need [constant] network access for this mapping.
