For backwards-compatibility reasons we have to live with INSENSITIVE in 
any case.
I agree that the semantics are somewhat unclear.  ATK does have 
STATE_INDETERMINATE now, to cover just such situations as a button which 
is neither-checked-nor-unchecked; this is a corner case of course, but 
it turns up surprisingly often.
As for SENSITIVE being misleading, one could say that the visuals are 
also misleading, since the usual meaning of a "greyed-out" element is 
"not enabled".  I believe that it is this subtlety which is driving the 
use of two separate states here.  Of the two, ENABLED is arguably the 
more important, and it's quite possible that AT-SPI/ATK clients which 
are currently testing the SENSITIVE state ought to just be testing 
ENABLED instead.
