I would say, if you want your change to apply to GUI's, and other
conceptual things like 'bzr down-thread' in a loom (that builds on
switch) - then you should be hooking into MutableTree or Branch or
whatnot. If you specifically want to affect the CLI, then hooking into a
specific Command object or wrapping one is appropriate.

We have plenty of examples of both, and many of them have turned out
well :)
