We have a stainless steel one from JL, must be fifteen years old. It does, however, pour hot water with the sort of accuracy you'd expect from a bloke who's spent every afternoon and evening in Wetherspoons for the past fifteen years.
For that matter, I've no idea who designs spouts, but if it's you, I'm a man that has a very particular set of skills; skills I have acquired over a very long career. Skills that make me a nightmare for people like you. Seriously, pyrex jugs, you cannot pour. Why are you jizzing stock over my hob? You're a jug. It's pretty much your job to pour.
