You can jump with the stick now, but it is a double press (double press+hold to fly) and intended as a backup option only. Obviously, this is a change from before - however the "up stick to jump" leads to a ton of misclicks and control conflicts. Team is considering making it an option (likely post launch if so) to enable this (with double tap being the default backup jump) - but it will be with a heavy dose of caveat emptor should you turn it on.
Honestly, the controls do have a learning curve vs what you may be used to - but if you take the time to work through that and settle into your own new style, that is going to serve you very well in the long term. Whereas before the goal was "simple to learn but limited" (which is why things like grappling are a pain), the goal here was "full functionality, but may have a learning period".
