The most notable removal is done in the orphans script. This code was really never used. Brion introduced it in 2005, already disabled. I have all the respect for what Brion did. I just think it does not make much sense to keep code around for so long if it does not work anyway, and must be rewritten from scratch anyway now that we have multi-content revisions and such.
