Leaving aside the question of which property to use to trigger this behavior, I'd like to focus on the use case first.

When we were working on the current version of writing-modes, we used to have `text-orientation: sideways-left`, which would support this combination of arabic/persian/hebrew/... and chinese/japanese/... where everything goes downwards.

Implementing it was a little more complicated than the rest so browsers were reluctant, but I thought that this made a lot of sense, so I tried to look for evidence that this was needed.

However, after asking around, I could only find people who agreed in theory that this could be nice, but no actual person who actually wanted to do that, or examples of (non-web) documents where this style was used (other than a limited body of Chinese Islamic calligraphic art). To be fair, my research was not particularly deep,  but I asked a number of people who should know better than me, and nobody came back with anything useful.

Given the lack of evidence of an actual use case, and the difficulty of implementing it, we dropped `text-orientation: sideways-left`.

Now, I still think it makes sense in theory to support, so I'd be very interested to hear if you have evidence of an actual need (either people asking for it, or documents using it).
