no, it is not. And I would rather not address this problem the way you 
do. If users are unloading pieces of their class definition from memory 
(eg. class destructor function imported from a dynamic library), then 
all objects of that type become unusable and I'd rather not touch them 
AT ALL, instead of risking undefined behaviour . Memory leak is "worse 
evil" than UB, because at least it is well defined.

I'd tell them not to unload dynamic library while it is still in use. If 
they cannot solve this problem in the first place, they are doomed to 
all other kind of problem - problems not connected to serialization that 
you cannot solve.
