"Locked" receivers in BNF models.

Firstly, I 100% understand why this is done and have no issues.

I just have one request:

Is it possible you can include an "unlock" feature for an additional fee with a programming cable? I have seen it available on the AR7210BX heli receiver that came with my 270CFX BNF. I'd like that with the rest of the spektrum receivers, if so I'd actually consider buying a BNF plane.

I wouldn't mind paying the extra 20$ or whatever to not have to rip out the receiver and sell it, and then buy a replacement and install it.
