a question about alt

Once the arguments for omitting the alt attribute have been thoroughly
reseached. If it turns out that there are legitimate cases for indicating
that no alt has been provided, what would the arguments be against using
alt=" " (quote space quote) to signify an image that for which an alt has
been provided?

This would differentiate it from cases where the author has not provided an
alt attribute/text on images that are not "critical content" out of
ignorance or laziness.
