Hmm, I seem to have seem different but maybe I'm dreaming.

In this particular case, I haven't "lost" anything since all of
the files are generated files, so it's easy for me to restore
them.  But I had a sort of embarassing moment with what one could
loosely call a "customer" when I told them something was there
which wasn't, because I hadn't noticed they vanished.  In this
case no major harm, customer is internal; however a few revs
passed before someone noticed so uncommit-revert is also "too late".
A colleague suggested that tools-using-bzr might like the current
"bzr rm on commit" behavior better so I'm not sure quite what to
say; as a command-line user I don't like it.
