The most I've ever heard of or seen out is 4, but that's if the stars align. Usually it's less (breakdowns, lunch breaks, etc.).
I think that yes, the next "big step" would be seeing more and more vehicles out on the line. I would personally (selfishly?) rather see the 50 km/h speed restriction lifted, first! Dying to see top speed on the spurs, especially with a nice cloud of snow kicking up behind.
