You can probably drill SREs that way but you are only teaching them how to _react_ efficiently, not how to _fix_ unique unicorn root causes of these failures. Aviation analogy would be an airplane engineer that tries to drill himself for in-flight engine failures AND engine debugging / engine redesign both at the same time.
It never made sense in software engineering, and never will. Minute spent on drills is a minute better spent on reworking codebase to reduce changes of future incidents. This post is very SRE centric.
