Sure, one can write a serialization library that makes this kind of
definition impossible. My point is that in principle it is possible and if
there is a general agreement to refactor important libraries to reduce
physical coupling then it is something that can be done.

This is even more important for a library like Serialization because any
data type may need the ability to be serialized yet many (most?) programs
that use such types will not serialize them.
