> Do you also take exception to braile translations replacing "red button" with "third button down"?

This is a different case for two significant reasons:

1. Utilising purely sensory references in web materials is a violation of WCAG success criterion 1.3.3, Sensory Characteristics (level A)[1]. Naturally, if you're physically brailling something, it's probably not web content but the point still stands: if your web page tells people to press the red button on the left it's not accessible to some.

2. By including alternative instructions in some form/format (or just making them inclusive from the start), you're not asking anybody to out themselves as having a permanent or circumstantial disability. You're just preparing for the case that they do. This is assuming the alternative option is available to everyone (e.g. on a web page or as a physical braille sign), rather than as something that is locked away and must be explicitly requested.
