I think most folk with no relevant experience will be contributing to an
existing project (its much harder to start a new project than bugfix an
existing one); few projects allow $random to push directly into their
branches, so I don't think its a reasonable default for that case.

I don't think that that advice was given (using bound branches is not
the same as having push and pull use the same url). If you want to use
push and pull, certainly given them the same url.

You can even do:
 bzr branch foo bar
 cd bzr
 bzr push :pull

to trivally set it up.
