Elevating such a strategy to a SHOULD as a work-around for broken middleboxes that might (hopefully!) be fixed in the future seems like a very wrong direction for the WG. 

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.
