Francis, I don't think BCP status would change this; that's still a 
IETF consensus document.  Maybe some implementations could fix their 
implementations with local hacks without as easily becoming (on paper) 
incompliant but they can already do this in any case.

However the goal of the IETF is to "make the Internet work better" 
(BCP95); I see significant value in finding out what works best and 
specifying that and revising that specification as necessary. 
Instead of leaving each vendor in the dark and invariably doing lots 
of corner cases wrong.

Maybe the critical thing that has been missing in the RFC3484 
discussions has been "have vendors already fixed this? how? which 
approach has worked and which not?"
