Well, I have a mixed feelings. In short, my main argument for ```section``` is that it has header and looks like a separate logical block, not just visual one (even knowing that it was initially planned for VR patch). Also I'm not sure whether it's valuable to emphasize date group as separate region for accessibility purposes. Even if we decide to use ```div``` probably we'll need some aria attribute.

Although it's not that important in this particular patch as both ```div``` and ```section``` work for me, I'd like to use that chance to better understand where in SMS app we're going to use ```div```'s vs ```section```'s and vice versa if you don't mind :) 

Soo, could you please share your thoughts on that particular case and in general for SMS app?

Thanks!
