Well, yes, hence my specifically mentioning the 16+ years that have
passed since WCAG 1.0 and HTML 4.01 were published. I was referring
to them as evidence of the historical situation, not as any sort of
recommendation as to what to do now.

There were several bits of WCAG 1.0 that seemed to be expectations
that every web site in the world should work-around various ridiculous
bugs in specific screen readers of the time, rather than that the
vendors of those screen readers should spend a few hours fixing their
buggy software.

I agree; I think the software has moved on considerably this
millennium and there is much less need for bug-compatibility with
very old user-agent software these days.
