Sounds like the UX designers for the new applications didn't understand the requirements. I worked on two web app projects that required to be usable fast and with keyboards only. It's not that hard, if you define the requirements right.

Also no scrolling was a requirement. This was done by defining a min and max screen resolution, and designing everything exactly for that. The app was supposed to be used exclusively full screen, so no need for responsive design.

The result was a bit like a video game, very few loading delays and instant responses to user input.
