And as I said, based on experience (*), arguing on which one is more 
correct would quickly wind up in an endless discussion as the number of 
participants goes up.  I could or could not agree with now, but only to 
have someone else arguing for the current semantics in the near future.

So I'm much more interested on which one is more generally useful to the 
most users.

Robert's reply seems to indicate that the serialization library doesn't 
require the current semantics.. is that so? can this be verified?

Only if so we can discuss whether the current semantics should be replaced.

(*) This month Boost.Optional (well boost 1.30.0) is turning 6 :)
