Well, I don't want to get into a too long discussion on Feldenkrais, his work etc. I agree the cited clip is a little unrealistic. (I'm not sure how representative that clip is of Moshe's actual approach, though). However, it bears pointing out that Feldenkrais tested this kind of thing with live weapons, against resisting opponents, so there may be something of value to be mined from that book.
For a more modern take on chokes, grappling against weapons etc, I'd look to ISR Matrix
. Unsurprisingly, you can kind of trace ISR back to judo (by way of BJJ / SBGi) too. I think Floro Fighting Systems *might* have some focus on limb tying / passing akin to a two-on-one, armdrag, step around to the back. You could argue that hakada jime is one possible finish from there (assuming you use the takedown hadaka per Feldenkrais cover).
Personally, I think the issue with choking some is that it's too slow. 5-10 seconds can be an eternity. But, as I said, opinions vary, and surely it's better to be behind the guy with the knife then in front of him.
