You're not the sort of user who would benefit from this patch, 
because you know way too much about bzr.

Yes, bzr has a better, more correct approach, as you've shown.  
But it involves relatively unique features.  So, users don't know 
to look for it, and would not reasonably infer its existence 
based on experience with other tools.  Their ignorance leads them  
to use less optimal methods.

If they read the documentation, they might do it the right way, 
but that almost never happens.

It also doesn't help that "checkout" means something different in 
bzr than in git, hg, and bitkeeper.
