I'm not sure I understand (or rather, I'm sure I don't understand),
but wouldn't:
<img alt=" " ...> (your proposal)
be equivalent to:
<img alt="" noalt ...>
wrt backwards compatibility?
noalt here meaning "there is no applicable textual alternate" (i.e.
similar to not using the alt attribute at all in the current draft).
