plugin section has lot of plugins most of them unsupported and not updated offering revisions and autosave disable and deletion of revisions.
forums are flooded by ppl havinf issues with their databases and probably having to look for third party plugins to do something most ppl need is wht is moving ppl to use plugins that at some point can break their installations.
it would be good to add a setting option for revisions and other for autosave
if you want it to be great adding tickboxes in post page next to each revision like in media library to delete them manually would be great
but option in setting to disable it would be more than enough
the less plugins
the less problems with databases as wordpress get updated, better performace of wordpress and less mails from hosts about a wordpress blog getting too much resources.
also less post from ppl with problems in their databases as there will be less plugins playing with wordpress intalls databases.
