Andrei is working on the design of the D collection class library. After
much thought and research, he finally came to the conclusion that a
collection class should not allow the address of a member to be taken. I
think his reasoning on the issue is pretty sound, and is consistent with
your take on it.
I wouldn't call it research, but I agonized a fair amount over it. I
think Phobos containers will all use malloc, realloc, and free for their
own storage, while still being safe.
