Ornn Destroyes Azir's Wall?

I understand that Ornn SPECIFICALLY has an ability that destroys player made terrain. But watching this video, I was reminded that Azir does not technically create terrain, as it's a wall of soldiers. A shield line, not a piece of land. Yes, the soldiers are sand, but they are still entities, technically, right? Then there's the wall Yorick summons, as a counter argument. It's a wall of flesh, more real than Azir's soldiers, but this wall isn't exactly sentient or mobile, and it provides no use but to stay still like terrain. I just was just wanting to put this out there. Perhaps Riot may take this into consideration and make a possible change in the future, to Azir's wall, or that whole interaction between Azir and Ornn.
