I recently had a conversation with someone in IRC who wanted to edit his
revisions because they had the wrong committer ID.  I told him 'No!
That's forbidden by the model!'  And I got this sense of deja vu, as if
I was still working on Arch.

I think it's irritating, at the very least, for bzr to store
likely-wrong information in perpetuity.  It doesn't seem fair to the
user, who might be quite willing to correct it, given a warning.  And
there have been situations in which I thought the committer ID was set
correctly, but it was not.  Those bugged me.

I dig that.  It's very nice to be able to say there's no step 4.  We
could simply set it the first time out, and tell the user what we'd done.
