AC: I don’t think it will replace the meta element any time soon, support for @viewport is minimal so far. I also note that the spec references a PPK article similar to the one I linked to before for the explanation of layout approaches.

[Jason] “Any time soon” is probably a shorter period than the life span of WCAG 2.1, however, which is my underlying concern.



AC: It could be dealt with as a sufficient technology thing, but I think it would need a note by the SC for such an important exception.

Otherwise there is a whole class of devices (the majority now?) that appear to undermine websites trying to apply this SC.

[Jason] I have series concern about any statement (in a note or otherwise) that says “If user agents …”. Most authors don’t have control over which user agents access their content. What user agents do will change over time, too.

I would suggest addressing user agent behavior in the set of technologies relied upon, and noting it in a suitable place.

David and I have been updating the page, worth another read, we’re up to 4 versions now!

[Jason] Excellent. Thank you for keeping track of the ideas as they evolve.
