While I am curious on what kind of usage might need more than hundreds or thousands of seconds delay? ;) 

I'm imagining a feedback delay or looper application a la Alvin Lucier's "I am sitting in a room" which is a ~90 second tape loop continuously fed back into itself. I think that the any length the standard decides on would be somewhat arbitrary, and possibly inhibit some creative or functional applications.

If the AudioParam were more extensible then it could be customized towards whatever the application needs are.
