Yes, see

I think this should be mentioned in some appropriate place in the bzr
help too, maybe 'help launchpad'.

It gets linked to all of them.

That would be great.

Yes, we talked about this.

It depends on launchpadlib as a client for the REST web services, so
it would add that library and its dependencies.

The current launchpad integration uses an older and simpler (cruder?)
xmlrpc that can be called using python standard modules.  This will
add some considerable dependencies.  We think it will be ok to add
them as soft dependencies, meaning that you can only eg do lp-submit
if you have them, but otherwise the rest of bzr will work.

There may be some extra work here in building binaries which include
these libraries, but it's still a step forward.
