Then you're using the same markup for two different semantics: one
case where that markup means the presence of an image is irrelevant
and the image should be ignored for the document to make sense, and
another case where the presence of the image is important and must be
announced by the UA for the document to make sense.

It's been shown what accessibility arise from that, and we're
discussing solutions.  But saying that "a text alternative is required
for all images" for accessibility because an accessibility standard
says so begs the question.

In which case, the author's tool, in an attempt to produce conformant
HTML, will insert alt="" or something even more harmful.  Making
something a conformance requirement won't force novice authors to
suddenly start writing good content, but it will encourage authoring
/tools/ to generate markup for the sake of conformance even if it
defeats the purpose of the conformance requirement.
