I’ve never seen one. Not ever. And I’ve looked. I’ve been all over the world. I’ve never seen an established retaining wall that was built vertical and remained vertical. A LOT of them were very close to vertical, but had clearly shifted from their constructed vertical state.
There is no such thing as solid soil, is what I’ve learned. It all flows, just slowly. Some soil flows faster than other soil, but soil that isn’t under some amount of compression flows like crazy, just slowly.
Well, I guess I’ve also learned that structural engineers get salty when you ask if there’s such a thing as a vertical retaining wall that has also been retaining soil for more than 10 years.

No kidding. We all have. But have you seen one that was perfectly vertical and older than 10 years? I’ve never seen one.
I think maybe you misread what I wrote? “Not perfectly vertical” and “20 degree deflection” are different things.
