I've played around with this (https://jtree.treenotation.org/designer/#standard%20iris)

I don't think you can make a breakthrough through syntax alone. I think you've got to integrate some type of live semantic schema, something like Schema.org. If I used "bsv" and didn't just get a slightly better parsing experience but also got data augmentation for free, or suggested data transformations/visualizations, et cetera, then I could see a community building.

I think perhaps a GPT-N will be able to write it's own Schema.org thing, using all the world's content, and then a BSV format could come out of that.
