Feel free to fix this.

My thoughts was that if a param is exposed as a dparam and a gobject
property then only one should be used at a time. If one is used the
other should be disabled. It would be error-prone to try to keep 2 param
subsystems in sync. Since your app knows about the dparam you can just
use that to query the current value.
