You should know there are no statistics on the various situations, let alone any engineering calculations. Unfortunately there are few situations that are the same and could be due to different details/plans/conditions/climates.
The practice of keeping the nails or screws well away from the wall/ceiling joint has been a common practice for about 50 years around here.
I expected some problems with my own lake home (I held the ceiling sheet rock nailing away from the wall/ceiling joint) that had 9' walls and scissor trusses spanning 28', but the house had tremendous thermal storage. Maybe the height of the walls provided some "give". But it saw winter temps at up to -42F and then heating up to 70F before I got there for a week-end thanks to a programmable thermostat.
Despite being an engineer, I can only offer anecdotal observations that would not be adequate for requirements on the code committees is an active in.
