Besides, the actual shutdown can--and should for "special case 
hardware"--be done with a script.  Just because there's a dbus shutdown 
that integrates with your desktop-environment shutdown doesn't mean 
MythTV needs hacks to deal with the intricacies of different hardware 
shutdown/suspend requirements.  It means that either a) the DE needs to 
handle those cases or b) you need to handle them with a custom shutdown 
script.
