What can they add now?

Blood pressure would probably be nice, but I imagine it's probably difficult to get accuracy in an apple watch style device.

Measuring BP with a watch is probably most accurate while lying down, eg during sleep, given yesterday’s Blood pressure should be measured lying down: study https://news.ycombinator.com/item?id=37471354

Galaxy watch 4 and later have it

There are some caveats to the BP measurement on the Galaxy watch, I'm not too surprised Apple isn't quite ready to implement it with similar requirements. They're probably holding out until it can be an "it just works" feature.

[kyriakos]

Yeah it requires calibration using a "traditional" BP monitor before using which means it doesn't just work...

[SirMaster]

Oh cool.

I hope they add it in the Watch 10 then.

Maybe since 9 is such a small change they have been working on a bigger change for the 10.
