Ah, sorry. Of course instead of "sighted/non-sighted" I should have said
"when UAs display the image/when UAs don't display the image or expose
alternative available to the screen reader"
Pedantism turned out to be useful, because when the issue is phrased this
way I now see the problem: the image may be displayed and at the same time
a screen reader may want to access alternative content.
This makes handling of interactive content in fallback tricky, as focus
required for the screen reader (needing to activate link in <picture>)
would differ from focus required for GUI users with images displayed
(never focusing <picture> content).
The easy workaround for that may be to treat <picture> fallback/alt
similarly to <button> content, i.e. just forbid focusable/interactive
elements. Do any UAs allow users to access <a> in rendered <object>?
