Probably most witnesses never heard of shutter step.
They just know, download the latest, patch, reboot, replay. (when the developers say so)

I do hope this fiasco does lead to better planning.
Instead of developers upset that they have to waste time telling "know nothing" witnesses what they are doing, having to painfully walk them through it...

Or witnesses trying to understand what is going on, don't because they are not in the loop and can't get in the loop because they are not a programmer and spent all their nights reviewing code.
