Well, we can certainly change that... The SASL code isn't set in
stone, it's certainly possible to architect it such that the old code
is used as a fallback if the new code hasn't been initialized.

Why is that so? Assuming we make it such that the old code is a
fallback, old clients linked against a new set of libraries will
simply continue using the same code (and same functionality) as they
used to have, because they'll never call the init function.

Naturally, that is another way to do things, and would avoid this kind of mess.
