Will this interrupt come back later, as part of the PCS? Or will the
PCS be polled?

This leaves this counter unused, as you said. It does not look trivial
to remove it, it is part of the statistics ABI. But if the interrupt
comes back in a later patch, this counter could also be brought back
to life?
