I think this can be a good solution for a lot of recent discussions about ditto/doclister and help all users to have a nice upgrade experience.
Of course, not all extras can be checked, but we can do for more important and critical.
Is just a plugin, easy to config and update in any new evo version and remove it when we do not need it anymore.
We can bundle in next releases for some times (from 1.4 to 2.0)
