I'm saying have a switch, or trigger pull, or something to put it in "sit mode" where you tell it 127 specifically. This won't result in a much different system than just no calling the pwms, but it works perfect (and you can do it on more than 2 outputs).

We used to have a psuedo-disable that just 127'd all outputs and it was used routinely during programming/debugging. Hundreds of hours of robots with 6-10 victors all content with their neutral signal and never moving.
That's news to me... I'll have to try that out (since an unplugged joystick reads as exactly 127, it's a really easy thing to test).

Thanks for letting me know about that -- this is exactly the type of advice I was looking for. I'll let you know if it doesn't work for us -- I thought I tested this before (with differing results from what you obtained), but I wasn't very thorough about it.
