I'm not sure if you've followed the other threads, but the "release on
first use" (oneTimeOnly) approach is broken; I hope nobody else is
implementing that.  (I don't know why it's in the spec; it's a poor,
error-prone interface, and it's inherently not interoperable.)  The
"release at the next stable state" (autoRevoke) approach is much more sane.
