Comment:
So on consideration I'm going to change my vote on this.  I don't think 
we should just put them in the tarball, because then we'll be shipping 
something that's not necessarily at the same level of testing as the 
core, and those problems are more likely to be found at release time and 
to delay the release.

What I'd rather do is: for small things that would make sense built in, 
and that perhaps are separate for accidental reasons, let's merge them 
in, give their previous authors core access, and add at least smoke 
tests for them if there are none.   I would include in this: extdiff, 
interactive,  bzrtools, bisect, diffstat, webdav.

We always intended to try experiments in plugins and then merge them, 
but we haven't closed the loop as much as we should.

For things that are large, undesirable to some users, still very 
experimental or have substantial dependencies like bzr-svn, they're 
better kept separate.
