I have NSOutlineView bound to NSTreeController
Additionally, I have a button, which is bound to "canRemove" of
NSTreeController. Unfortunately, button never gets disabled (even if I
have an empty selection in NSOutlineView)

I've run into this before and in my case it was because I forgot to bind the Selection Index Paths of my Outline View Content to the selectionIndexPaths key path of my tree controller. Forgetting this setting caused additional problems like insert: inserting after the last-created entry instead of where the selection in the UI was.

Do you have this binding set on your outline view?
