Because invisible data rots (see: <meta> keywords).

That's a crucial difference between @summary and aria-describedby. The  
contents of aria-describedby can be made invisible, if the author  
wishes. The contents of @summary cannot be made visible.

Personally, I think that this distinction that @summary draws between  
users of AT and other users isn't a helpful one. If history has taught  
us anything, it's that accessibility features turn out to be useful  
for everyone (e.g. the invention of the typewriter or closed  
captioning on television).
