It is primarily an artifact of C++98 legacy, but removing it is quite

However, the basis of my comment is that the hackery comes at a cost. There
are some cases where it makes such a huge difference that we essentially
have to use it (being able to memcpy large data structures for example). It
is not at all clear that eliminating the tombstone splatting is a
sufficient motivation, and increasingly with C++11 these should "just work"
thanks to the standard-based type traits being compiler enforced.
