Technique is the issue. Unless it is a huge stairwell, and it's 100 degrees out.
I could see putting extender in wall paint, I just have always managed without it.
Paint the stairwell when it is cooler.
Did I mention technique? Do whatever it takes to keep a wet edge.
Use two people if you have to.
Use a small nap and just roll up and down without worrying about finishing all your strokes the same direction.
Wet edges always takes priority over nap direction.
I often finish stairwells all up.
Sometimes I use a plank. finish a high part, jump down finish a low part.
Or a 2nd person low rolling up and feathering into the upper areas. also rolled up.
Blah, blah, blah.
