4. pitching moment from the flaps slows the plane
5. crew is too distracted by #1 to act on the speed decay vis-a-vis power or trim, and too task saturated from everything. They only pull back more on the yoke to counteract the descending tendency, thus slowing the plane more

Planes have been stalled for stupider reasons than that, so I believe it.
This ^^^
You can’t compare a multi engine jet with a light SE.
In a light GA aircraft you simply don’t have the excess power or performance.
Inexperienced pilots or pilots with very marginal currency should avoid flap extension or retraction in a turn. Climbing or descending.
I always instructed my students not to do it.
During a turn you should be concentrating on other things and aerodynamic changes are a distraction.
