Really? Do you have data showing that is the case? All the data I have
seen indicates that @summary is used extremely rarely, and when it is,
it's often used in the wrong way.

It seems to me that the WAI already has come up with a better
solution: aria-describedby. This attribute has two advantages:

1. It encourages the description to be visual to all users, not just
users of AT tools. While still allowing the description to be only
visual to AT users when that is desired by the page author.
2. It can be applied to all elements, not just tables.

This attribute is already supported in HTML5.
