[Split Tab] How should the split tab proposal be extended if browsers start supported more than 2 split tabs?

From @tomayac:

Was it considered that in the future there could be more than two split tabs in a browser tab? At the moment, the baseline assumption seems to be that there are at most two. I can well imagine that browsers would innovate more, and, for example, on wide screens allow a tab to be split in n split tabs.

I would agree that there are likely use cases where greater than 2 split tabs make sense. E.g., product comparison where a site opens product A, B, C side by side. Likely though, there is a limit to how many tabs can be useful to see at once, where any more than that limit is too much info for the user to digest and actually makes the experience worse rather than better.

To note also: the product comparison layout is possible today, but I imagine it's a pretty large lift for site authors to create. Being able to open into split tab might be easier

i like idea to split one to horizontal too, so you can really do multitasking, it is like muxing on linux then :)

If split tab was two unique tabs with a splitId property and only displayed differently, there wouldn't need much changes in already existing API..
