What is the use case driving your desire to make this change? BTW, the
spec (both RFC 3921 and rfc3921bis) says this is a SHOULD (not MUST). If
you want to send roster pushes to active resources that have requested
the roster, feel free to do so on an experimental basis and report back
with your findings. I happen to think that the vast majority of clients
don't hang around in the active-but-not-available state, so I doubt that
there is a lot to be gained here. But again if you have some powerful
use cases, please do share them.
