Can't help but think that, possibly, this binding post flex might be a good thing, too. As putting stress on a connection point could lead to a more severe failure, allowing some flex may be a design point to alleviate such a failure.
I'm only guessing, as my sense of a quality build would prefer a rigid connection terminal.

So it probably comes down to such factors as cost-to-implement and whether or not its even seen as a problem in the first place. *shrugs
I suspect we would hear much more about this if peoples gear was shorting out and exploding?
