I consider that your argument is based on a mis-reading of the WCAG 1.0
guidelines.
1. WCAG 1.0 states
"5.5 Provide summaries for tables. [Priority 3]
For example, in HTML, use the "summary" attribute of the TABLE element.
[http://www.w3.org/TR/WCAG10/#gl-table-markup]
The checkpoint does not normatively require the use of the summary attribute it
normatively requires the provision of summary information for data tables. The
example of the summary attribute is from the techniques document which is non
normative.
The abstract of the techniques document states:
" This document is intended to help authors of Web content who wish to claim
conformance to "Web Content Accessibility Guidelines 1.0" ([WCAG10]). While the
techniques in this document should help people author HTML that conforms to
"Web Content Accessibility Guidelines 1.0", these techniques are neither
guarantees of conformance nor the only way an author might produce conforming
content."
[http://www.w3.org/TR/WCAG10-HTML-TECHS/#table-summary-info]
the most pertinent part of the above quote is;
"nor the only way an author might produce conforming content."
So authors can still provide summaries for tables that do not involve the use
of the summary attribute, but can be considered as conforming to WCAG 1.0.
