IMO not. The players should support it themselves, as we already do in Amarok. 
That way you would end up with double suppression and nasty corner-cases, plus 
MPRIS was never meant to do this job, I'd consider it an abuse.

Neither this, not every sound playing is the reason to block power management, 
think of notification sounds, naughty flash applet having an audio stream open 

Generally I think we should consider power management inhibition a very 
privileged operation and use it only in justified situations with no right of 
false positives.
