ARM is terrified of RISC-V and this move seems to be an attempt to prevent anyone doing a lift and shift away from ARM. RISC-V is a minimal CPU as a manager for a lot of co-processors hanging off it. What ARM has said is "you can't put your own custom co-processors near an ARM core if they duplicate functionality you could license from ARM". This would prevent you from designing a CPU with an ARM core and a ton of custom co-processors, and then swapping out the ARM core for a RISC-V.
