I recall in shop class in 1968 you would receive 3 licks if caught

I think some guys were and are unreasonable... I cannot tell you how
many times I've uncovered defects on the first jointed edge or face of
rough cut that led me to joint the opposite edge and/or face so that the
defect would be removed by the thickness planer or saw in final
dimensioning... I see it as a lack of reasonableness in their position
on things.

Then you would proceed with straightening the opposite edge as usual with
the TS, flipping the board, and cutting the board to width with the defect
on the waste side.
Same would apply to a face with a defect.

That depends on how uniform the board was to start with, and other
factors... It is not unusual for me to find that the rough cut board tapers
in thickness and/or width with the result being that much more wood is
removed from some areas than others during 4 squaring. Add in discoveries
about twist, cupping, checks, figure, grain direction changes, etc. and
changing the initial reference surfaces during preparation is not unusual at
all. Of course if grain and figure alignment and surface quality don't
matter for the intended use this doesn't matter much... just cram it through
like framing grade dimension lumber is prepared!
