I think that what Zero does in the way of programming changes has more to do with what they think will sell more motorcycles to their future customers and less about what can be done to keep some current owners happy.  While I agree that a smoother transition between on and off regen when slowing down to a stop, or when the battery is at 100% and not accepting regen for more than a second or two before shutting it off would be nice, I am pretty happy with the way that the system currently performs on my 2014 S.  I just shut it off when the throttle is closed and coast, while letting it supplement my braking when I touch my front brake lever lightly. That works for me.   :)

When I said "everyone wants something different out of this feature", I meant that literally we're all talking about different goals.

I was responding only to the idea that some enterprising third party could easily patch the firmware and make a worthwhile amount of money.

Honestly, the word "trivial" is one of those words people use about software development that I always regard with skepticism, because I know it means only casual consideration for how it gets made. And nothing about hardware control by software is trivial.

The Sevcon does not support an implicit regen ramp up out of the box and isn't motivated to because their larger market is served fine with how they do it now.

For what it's worth, an implicit ramp creates some slight difficulties making regen work right if it's toggled too quickly.
