Ok so you have provided one more class "map sites" still don't add up to
much.

>previously mentioned, Rorschach tests.

There is no consensus or even tide of opinion towrds this being considered a
legitimate use case for omitting the alt
both WCAG 1 and 2 conflict with this.
So really it's just you who thinks this is legit. I haven't seen *anybody*
else on the HTML WG defend your opinion on this.

We shall await the PF WG's advice on this and other matters related to your
definition of "text alternative" or "alternative text"

I did note what Henri sivonen had to say[1] on the subject in IRC, perhaps
you missed it:

[10:54] <hsivonen> Hixie: btw, I think WCAG 2.0 is rather reasonable about
the inkblot case and the HTML5 example takes "alternative" too literally
