Edit handlers/protocols UI

Chrome used to have an editor where you can remove, enable or disable protocol handlers. It seems to have disappeared without reason from Google Chrome as well as Brave.

While we can edit protocols directly in the user prefs file, is there any reason why it was removed? It seems like it’s dangerous to not allow people to remove protocols they may have accidentally clicked “yes” to. In fact, protocols can allow the launching of programs on the host PC. It seems like a huge security hole to not allow users to remove them or at the very least “clear them all”.
