sorry, no answer there, because they don't explain, why they have changed this behaviour in the middle of the lifetime of the soc. They can change such things before they go to market, but not after that, when the manufacturers already have tested, that their parts are working (and they have worked before). I think we should all send our cases back to the manufacturers, say them, that their cases are against the spec and demand our money back, then it's only a matter of days until this commit is reverted or the pi foundation goes bankrupt
I don't think the strict handling is a wise decision, if every part of your pi comes from a different manufacturer. Now we have cases that no longer work and we can't buy a new one, because we don't know which cases fulfill the specs strictly. And it's not the pi-way, to buy the parts from one single manufacturer or buy every year a new pi, that's the CoreELEC-way.
For me it sounds, that someone has made this change without reason and without knowing the consequences and now is happy to pass the buck to the manufacturers. But then the pi foundation should be honest and say: dump your case, we will never fix this and we cross our fingers, that your next case works
