I am sorry. I know this is unrelated to archive but what ever happened to
flyweight.

I think there is a significant issue with your proposed extension
mechanism: an archive can only contain a single extension object at a
time.  Consequently, if two types require different extension objects,
they cannot both be serialized using the same archive.  In particular,
if say flyweight requires some special extension object, and shared_ptr
requires its own special extension object, it won't be possible to
serialize both using the same archive.  It seems, therefore, that in
practice there would have to be a single standardized extension object,
which is either in use or not in use for a particular archive.
