Looking at "unique_ptr/boost/default_delete.hpp" as of SHA 6d294095747525ddb3a7481e374642156f5825ec:
* If you're in an environment where the workaround for C++11 smart pointers are in play, then you probably don't have sibling-constructor (delegating) calls either.
* When pointers are used for array new-ing, then cross-version conversions probably shouldn't be done, since U IS-A T doesn't mean that array-of-U IS-A array-of-T. (The spacing won't work right if the sizes of U and T differ. Neither will deletes unless a properly set custom deleter is used.)
