Choreology is an established discipline. There's no reason to re-invent it without improving on it. Some people might do it professionally. A big budget musical production typically will employ a choreologist to make notes during the rehearsals. Members of the company can ask for reminders about their parts, which the choreologist not only will have written down but will be a good enough dancer to demonstrate.

I've studied Labanotation and Benesh movement notation, among others, some on my own and tried my hand at annotating social dancing with it and didn't find it to be particularly useful for social danced partnerwork in particular. For Choreographed dances, I am sure having a choreologist on staff would be a god send. However, for improvised social dances, I don't feel like the dance notations that I have seen capture the cues and signals the lead sends to the follower in a way that is adequate to be learned from later on. If you have any resources about this though I would love to read them!
