I also think it's a bad idea to change some keybindings, especially if we know that some people like them and have been using them for ages. (I've gotten plenty of bad feedback for the users of my Emacs packages for doing such changes in the past) Changes to keybindings are considered breaking changes by many people and those should be avoided.

Sounds good to me, too -- we could bind those by default.
But I don't think we can change the C-c <left> etc bindings for those
that enable winner-mode explicitly -- I think that's likely to be very
annoying for those users.
