I don't use Jack myself (anymore), but from what I understand, this
feature is tied to jackdbus, because D-Bus is the protocol Jack and PA
use to communicate with each other. When PA is running and Jack is
started, Jack can't force PA to release the device, if PA doesn't want
to cooperate (well, it could use the "kill" command or something...).
PA cooperates by listening for device release requests using D-Bus, so
Jack has to use D-Bus too. And apparently jackdbus is the only
implementation that does that.
