Don't forget about alignment requirements.

I agree. Pimpl serves different goals. If the goal is just to hide
implementation details (but not necessarily avoid recompilation on
implementation change) this is very welcome. Though, soon, you'd verge
to a "opaque value_ptr" where the value_ptr could have clone-semantics.   

So, I can see a choice for "pure Pimpl" facilities, without any optional
stuff.
