It seems accidental. Instead of "we have a new brick type that only goes together once", what has happened is that there's a configuration of normal lego bricks that can get pinned into place.
A reviewer will see this immediately. Someone screwed up. They should hire an intern to simulate that and run a check in their modelling software.
For example, the 1x3 sloped pieces in some of the newer sets are super fragile near the edge. Similar pieces from many years ago survived.
It's unclear whether the modern set designs are putting new strains on weaker points or if the material quality is worse, but either way the result is a doubt about the longevity of the pieces
The worst were those grey pieces with clips on both ends and a 150-degree bend in the middle. So easy to break.
The few other brick manufacturers that design their own sets are clearly inferior in set design. Even Mega has a long way to go.
But you are right a factor to consider.
