This is the real point of contention for which we're unable to reach
consensus. I find it equally bizarre that an incomplete structure
should be considered valid output from an authoring tool, despite the
fact that the incompleteness means the resulting output cannot be
perceived by some people.

I don't understand your point here. If an author chooses not to
provide alt text, it's the author's fault that the resulting output
doesn't conform to the specification - not the authoring tool's fault.
The only time it would be considered the authoring tool's fault is if
the authoring tool made it difficult or impossible to provide alt
text. The solution to dealing with broken authoring tools is not to
make an incomplete structure compliant by lowering the bar, but
ensuring that authoring tools do provide a complete structure.

I think this is the point where someone mentions broken authoring
tools as scenarios that should be considered compliant even though
that isn't the case[1], and round we go until we're back here again.
