I don't really see how somebody could validly depend on the old
behaviour, given it always was windows only, and there only with
nonblocking sockets. Seems more likely to be an undiscovered bug for
such a hyptothetical user.
I also think there's rather few drivers / clients actually shutting down
sockets. Here it AFAICS really was a more or less unintentional side
effect.
