Actually, I know of at least one HN user who will read his comment in braille. GP provided plain text, which is accessible to braille screen readers. And HN is hailed in accessibility circles as an extraordinarily accessible website, so has a disproportionately large accessibility user base.

The point was supposed to be an example of a possible consequence of rules like this. Not a specific example of an actual consequence.

Your comment also suggests the same solution for the bread. If you don't like that there is sesame in it then you should build a robot to remove the sesames. That's the same as saying "I didn't translate my text for you but you can find some other way to get it translated".

Yup. Mandating the inclusion of such features in new construction should be required. Retrofitting is another matter that very well might involve pretty much tearing down structures and most certainly shouldn't be required.

(And note that in some cases "new" construction must work with existing constraints. I'm thinking of a sign I saw in Carlsbad Cavern saying no wheelchairs past this point. The loop that was denied wheelchairs contained a pinch point a wheelchair couldn't go through. Man made the path, nature put the rocks there.)
