Also, a well-implemented responsive design will cope well with whole page zoom, without introducing a horizontal scroll bar.

I agree that page zoom is not the same as independently scaling page text.

I also agree that page zoom under G142 can be used to meet SC 1.4.4.  But, I'd just add that it is also good to be aware that the horizontal scroll that is often a zoom by-product can cause significant accessibility issues by itself.

If only the text is increased in size this horizontal scroll issue can generally be avoided.

Page zoom (if not blocked or disrupted by the author) can be used to me SC 1.4.4 resize of text.  People may disagree on this - but this is current the case through sufficient techniques that were created by the WCAG working group.

Page zoom is different from font size change.

Personally, I tend to think it's the responsibility of UA developers to provide functionality like that to their users (e.g. https://www.w3.org/TR/UAAG20/#g-1-4)

I agree that this should be a UA thing. I'm merely asking if such a functionality is available in tablets, smartphones, etc. For example, iOS offers a Text Size option under Display settings in settings.app, but that doesn't translate to web content. I'm not familiar with any option on any mobile platform that offers such a functionality (text size for web content).

I skimmed 1.4, but that doesn't seem to say whether text should be scaled independently from he layout. In other words, is page zoom equal to text scaling?
