Sorry if this has already been suggested, but why not introduce a new

I think this is possible already, for the database people. The problem
is that it will not pass the is None test, which at the very least is
not backwards compatible with how they have used it before.
The new singleton will be called something else, likely with Null in the
name, so that's what I'll call it here... Null.
So when switching from None to Null, you must also switch from "is None"
to "is Null".
Of course it is not backwards compatible... but once all the "database
related None usage" is switched to "Null usage" it should work the same
as before, but with proper (for some database's definition of proper)
semantics.
