90 minutes is probably still comfortable time for an international flight in the US if you have Pre-Check. I don't like rushing so I'd probably give it a bit more time but usually things go pretty fast.
That said, I agree with the basic point that transatlantic tends to be an all-day thing (or a red-eye) and shaving some hours off the flight itself doesn't really change that. (And even if it made it easier to get to continental Europe on a daytime flight from eastern US, that matters less with modern lie-flat seating.)
