Seems to me just a lack of management support then. Too many suits, 
not enough engineers.

If $RANDOM_NET_ENGINEER says "hey, I can't reach $BIG_SITE any 
more!", and its because $RANDOM_NET's DNS resolver is broken, I[1] 
say "Tough, here's the spec, read it, know it, live it."

If $RANDOM_NET is starting to have queuing issues because they can't 
see the MX's for $BIG_SITE that might prove adequate incentive to 
actually find a resolver that follows the spec. :)

[1] That's _I_, definitely not the viewpoint of my own $BIG_SITE 
employer, unfortunately.
