No. We do not define browser UI or user experience. Many phone and tablet 
browsers do not support zoom-and-reflow today. (But they support interactions
such as double-tap zoom to quickly fit the designated content into your 
physical viewport and avoid horizontal scrolling, for instance). There are 
just too many possible scenarios and environments - in terms of device types, 
inputs/outputs, ebook vs. magazines vs. web sites vs. apps - to force 
anything on all UAs. And, quite frankly, little evidence that it is needed.

Whether and how the property should react to commonly implemented zoom models
is 100% orthogonal to whether browsers should support a particular zoom model.

If you want to keep discussing this topic, please start a new thread. Thank you.
