I don't know what its name is. It was proposed by Hans Boehm, and the
Android team pointed me to this discussion on a RISC-V mailing list:

https://lists.riscv.org/g/tech-unprivileged/topic/92916241

Searching with various terms suggests it might well be the Zabha
extension, ratified in April this year, but that is deduction.

Makes sense. It is not in itself "large-scale," but suitable hardware is
only going to be available if someone wants a lot of it, enough to make
building it worthwhile.

Yup. RISC-V established a lot of awareness, and some expectations, but
there hasn't been the equipment to let people start using it.
