Galaxy S6 :: Stop Samsung Keyboard Reenabling Itself

Among the slight annoyances I have with touchwiz, I really don't like Samsung's keyboard. If I disable it in input methods, it only stays disabled until I actually use the other keyboard/input method I have selected.

It turns itself back on and gives me a notification to select input method. As it's a samsung app, it can't be disabled in app settings. Would it be safe to just delete it completely? I don't think there's an option to disable the notification popup when you have multiple input methods turned on. extreme phone ocd

edit: nvm I guess, yolo deleted it, now to get rid of sfinder and QC in notification menu
