My understanding is that the slowdown is not a specific company this time - it's getting the PLIC and CLIC specifications close enough to done that the RISC-V Foundation can be confident that the Hypervisor extension will not need to be modified to support direct delivery of interrupts to guest IRQ handlers without hypervisor involvement.

Which is completely useless, since you can always make a subextension.
