Agreed. And the simple way to do that is with an attribute. There used to
be one for adding a summary of a table.

I don't think it is so important whether you think it is a long
description of a table or a concise summary. Some authors are better than
others, and will do a better job of communicating. Some spec writers and
educators are better than others and will do a better job of communicating
what the spec is trying to achieve. But I think it will take a fair bit of
effort to get a consensus around the goal, and I suspect that effort is
better spent on making and describing and improving real-world examples
than on trying to get the wording of the spec itself to be perfect - if it
is more or less good enough, we can focus on the real world.

Or many other things.

Yes, for the cases Gregory posits that require being element content,
using aria-describedBy to point to that content (which might be in the
caption element content, or might be somewhere else) seems like the
logical approach.
