If this were just a work-around for breakage, I'd be more inclined
to agree, but it is also a solid opportunity to improve performance,
because privacy-relevant changes of administrative control across
special-use labels should be very rare to non-existent.
So short-circuiting qname minimisation when a special-use label is
encountered seems like a win-win.
