Howard Hinnant mentioned[1] that it was mostly because no proposal was
made, and apparently experimented with such a thing himself (he
maintains libc++).  I'm not on the standards committee's reflectors,
but there was apparently lively discussion on shared_ptr<T[]> pointer
arithmetic.

Yes -- emphasizing more than just calling an explicit constructor.
