hello, we should be precise that disabled components (radio, check, switch must be used for non-informative elements where the user doesn't need them and their status (disabled) to complete the task. And read-only elements should be the ones that convey information, because they and their status are essential to understanding the page and the task to be accomplished..

Agreed, but I think this should mainly be in the guidelines for these components, we could still have a note on this in OUDS Web documentation. What do you think @MaximeTonnerre?
