Thanks for the link, I took my time reading that one
It does a good job of showing how the ship throttle will work with a physical throttle (I had no idea you could actually pull back on throttle controllers), and does a good job of showing how on-demand decouple works with a quaybored, but doesn't show at all how the throttle would work with a quaybored or how on demand decouple is expected to be used by players using a physical throttles...
So as everyone else said one to wait for 3.5 for. With my flying style (crappy) if I can find a ship with retros as strong as the main thrusters this might just work out for me, assuming this is all going to work with a keyboard and isn't just reserved for throttle controller players.
