This assumes that objects will only need to know how to encode themselves
for a single known backend, or that all possible backends can rely on a
single encoding. Both are very bad assumptions. (Not that most of the rest
of the recent discussion on how to "fix" DB-API is not equally as flawed).
If it were that easy, it would have already been done. However, it is not
an intractible problem, though it does _very_ quickly escape the scope of
DB-API and deserves a distinct API layer of its own.
