With implied bounds my gut reaction is that you get c++ templates without "concepts". Ie the situation c++ is in today, where it's perfectly fine to instantiate

With implied bounds my gut reaction is that you get c++ templates without "concepts". Ie the situation c++ is in today, where it's perfectly fine to instantiate a template with an implicit bound but you only get a super confusing error message later when you try to use a particular function that this bound requires.
