Reusing TXT is bad engineering.
Such a statement, unsupported by facts, has no place here; if you are 
going to refuse to argue your point or against the points made, why 
are you here?
If using TXT is bad engineering, you've done a dismal job proving it.  
 We're supposed to take your word for it?  While you blatantly ignore 
our arguments and questions?  (Which I even restated in my last post!) 
 Makes me wonder if you'd object to the Apple ]['s amazing hacked 
support for 16 colors even though it was designed for 6 as unaesthetic 
engineering. Or are you saying you hold the reins and will prevent a 
MARID proposal that does not use a new RR from getting RFC status, 
even though you can't provide a technical argument worth the bits its 
printed on to support your argument?  Presumably you can write well, 
since you wrote an O'Reilly book.  But on this topic, your arguments 
hold no water.
the reply above is not particularly helpful; accordingly, i ask that 
all participants kindly re-read:
