As far as I can tell, that's intended only for Igates, and only in  
response to a query as you pointed out.

It not only leaves out stations that are not Igates (i.e., nearly all  
of them), but it is also extremely verbose.  I'm all for readable  
text, but in the case of a fairly complete set of station  
capabilities it would be a huge packet of clear text as opposed to  
two or three bytes if one bit flags are used.  The latter would be  
compact enough to include in every packet.
