The only writing system for sign languages that has significant adoption ( https://en.wikipedia.org/wiki/SignWriting ) was developed not by a linguist like other systems had been, but by a dance instructor, who was inspired by such notation systems. It borrows many of the ideas about how to notate orientation and movement, and works somewhat like a phonetic alphabet. There is close transcription with every little join and variation precisely notated, and also a more abstract kind of transcription which assumes fluency where the reader can fill in the gaps.
As a sign language user, I wouldn't say it has anything near significant adoption, but I would agree in terms of writing systems for signed language, it's one of the most well known ones.
That said, I've never, ever seen it used in practice by people that use signed languages. Other than an oddity on the internet here or there.

I also immediately thought of Sutton SignWriting. (She also created a movement writing suite, including notation for insect movement.)
