The std::vector code is done this way. I assume(d) the library writers are
well aware of std::is_trivially_copyable.

Let me ask that question the other way around. If based on type_traits it
could be worked out (at compile-time) that double initialization can be
avoided, why doesn't resize() do the "right" thing on it's own? resize()
should do what it says it does, and do that in the optimal way, given T.
