How do you

  bzr diff -r revno:3:/path/to/branch..revno:3:/path/to/other/branch

with only two arguments ?

To do that, you'd need

  bzr diff -r 3..3 --branch-of-the-first-3 /path/to/branch \
                   --branch-of-the-second-3 /path/to/other/branch

And the problem is not only with "diff". Almost any command taking a
-r argument may want to access a remote revision. At least "cat" (and
the "log" command mentionned earlier) make sense on a remote revison.
OTOH, "diff" is the only case which come to my mind where it makes
sense to specify two revisions in two branches in a range.

The big advantage of a solution using one identifier to identify a
revision (whether it's revno:X:path or path;revno=X) is that this
identifier can be used in many places (cut-and-paste-able from a mail,
clickable on a web interface, ...) other than the command-line.
