To clarify... I not opposed to an API to list SD. But then it will be specific
to SD by design, so it is orthogonal to this thread's topic.

And most filters depend on parameters that cannot be expressed in a generic way
- you need to know what a given filter does to understand the parameters. I
guess JP Dinger designed the current (limited) filter API the way he did, with
this problem in mind.
