It isn't specific to shared_ptr.

Every proposal is evaluated on it's own merits, but lots of LWG regulars
look for "existing practice". How widespread that has to be is up to the
judgement of individual members. In the case of the STL, the LWG (and full
committee) were willing to accept the lack of widespread existing practice
because the perceived advantages seemed so great.
