It’s one of those abstractions that’s feature complete and stable, and looking at NPM it’s apparently getting 6.5mil+ downloads a week for some reason.

Lately I’ve just taken the opposite view of the author, which is that we should just use streams, especially with how embedded they are in the `fetch` proposals and whatever. But the tee critique is devastating, so maybe the author is right. It’s exciting to see people are still thinking about this. I do think async iterables as the default abstraction is the way to go.

Adding the staff is 37 codepoints versus 36, but I think using ZWJ would at least have each numeral independently renderable so it degrades gracefully. I’m not too sure about how combining characters degrade.

Essentially it boils down to whether you think the staff and the digit flag part of the numeral are independent or not.

The 4-stave system is interesting but can almost certainly be done using ZWJ hacks maybe.
