Wayland itself has rotation support, but GNOME provides no interface for it. I have this vague memory that I somehow managed to get a Wayland session to rotate its displays with xrandr somehow, but I've never managed to replicate that; apart from that one time (if it really happened...)
This is not really factually true.
The Wayland protocol does not have display configuration (ie the equivalent to XRANDR). GNOME shell provides a D-Bus interface for display configuration which is what drives the control-center display panel, and that D-Bus interface does support rotation.
The X11 implementation in mutter is translating it into XRANDR and does support rotation. The Wayland implementation translates it into libdrm calls, and does not support rotation yet.
OK, I must've had it garbled. The result's the same, anyhow.
I could also quibble with the notion that "I happen to use a rotated monitor on my system, so rotation is a test blocker",
Well, feel free to quibble with that notion, but it's not what I said - I just said that it was a blocker for my daily use, because I'm not going to use non-rotated displays. I didn't say it was a "test blocker".
