Forgive me if I'm wrong, but the proposals don't explicitly ban the use of throttles, the stipulation is that the pedals must be turning in order for the motor to provide assistance. So you can still have a throttle, simply acting as a variable assist control, overriding a minimal pedal activated current, and cutting out at the same time. There is no stipulation about how hard you must be pedalling.
This has been an option on the Wisper, certainly since 2008, which is implemented by connecting the purple wires at the controller.
It then becomes a simple case of adapting one's riding style to comply, and getting a little more aerobic exercise in the process.
Also, the proposed change may allow the use of throttle only power up to 6km/h, which should be enough to get you started if you can't manage the initial push.
