I dont think that is entirely correct.
Level and heading changes for weather are not usually a problem and if it suites dropping out of the airway is another option so even the SEP pilot has similiar options to being outside the airway albeit it does require some fore thought.
It really is up to you whether you plough on through a front with tops higher than forecast that you could see from 30k away.

It would seem things have turned out much better than you forecast which makes a change given all the talk about much worse than forecast weather.
PS Why is it the weather is always worse than forecast and never better.
