Ugh, sorry. The chromestatus tool reminded me to fill in many blanks, but not the basic ones like the version numbers and platform support. I've updated the chromestatus page <https://chromestatus.com/feature/5136319775899648> with more info now, but see below for the specific answers.

I've checked that box, and added a bit more text about it. There's an important distinction here - the APIs will be supported across all platforms. But not all platforms (e.g. Android mobile) have a way to show split screens. On those OS's, the fallback path will be taken, to a new tab.
