From emacs-evil/evil#992:

I'd like to think of evil-collection as serving as an alternative evil-integration.el here, so the all or nothing approach should be fine.

Currently, evil-collection is mainly focused on keybindings and is not an alternative to evil-integration. I'm not suggesting doing any opinionated configuration by default, only adding "fixes" that it's unlikely anyone would object to (e.g. advising show-paren-function to make show-paren-mode work correctly in normal state, adding evil command properties such as :repeat, :type, :keep-visual, and :suppress-operator, etc.). Anything considered potentially intrusive could be optional. Unfortunately, since evil-integration is all or nothing and will stay that way, its useful, non-intrusive functionality needs to be replicated in another package for users who want to sanely only use those parts of evil-integration. Maybe evil-collection is not the suitable place to do this, but I'm interested to hear your thoughts.
