I think the above is OK for landmark.el (given that it probably has
0 users), but for something like crisp.el, it's probably better to
transition more slowly, e.g. with a release of two where it's both in
`obsolete' and in GNU ELPA.

Also it's good to add a Version: header to the bundled version, in case
the user also installed it from GNU ELPA (so package.el can know which
of the two is more recent).

I don't think that's practical (maybe some VCS will support this well at
some point, but currently I think it'd be too much hassle for too little
benefit).
