I know why you want this, but this is a little too wishy-washy.
Something along the lines,
"As we emulate execlists on top of the GuC workqueue, it is not
restricted to just 2 ports and we can increase that number arbitrarily
to trade-off queue depth (i.e. scheduling latency) against pipeline
bubbles."

Not that we have any evidence to suggest we need more than 2 ports ;)
