Has nobody tried to implement an aarch64 equivalent of the "x32" ABI? That is, using the 64-bit instruction set but keeping pointers 32 bits long?

There's Arm64ilp32, but I don't think it's in the mainline kernel and it's really bleeding edge/strange.

When aarch64 is so badly supported on pi, it's really scary to go even further into the fringe with Arm64ilp32.
