backward compatibility with binary-only drivers ...
Not that i care too much (in the end it is for the benefit of
a limited set of people which could as well not upgrade, vs.
preventing useful functionality to be added in a safe way),
but some people do and i can see their point.
On the other hand, this also means we can never progress if not
on major releases or unless changes slip in unnoticed...
