Actually, that's not true.
For a "lightweight remote checkout", the commit (even over a smart
server) would be more difficult to make efficient than locally because
the commit requires a potentially large transfer of data because you
need to compare the new files (on one host) to the old files (on the
other host).
For other situations, the commit is really a commit+push, and the push
is equivalent to a "pull", just done the other way around.  And if
you've followed Bzr development, you'll know that Bzr is not that great
at doing pulls efficiently and it's unlikely to improve soon.
