I'm a mobile photographer, and whilst I've been using bracketing on a Lumix TZ5, on Nokia 808, I've *never* used it on a Lumia (1020, 640 or 950). 99,99% of people use bracketing for HDR. Now you have RAW and RichCapture.
I seriously doubt, as Daniel in his article, that people were using bracketing, even amongst "pro" mobile photographers.
So I agree with your general statement, but I don't think it can apply to bracketing. Nobody bought a Lumia for bracketing, and to achieve HDR, it's probably the less relevant way to generate one.
Anyway, I was only reporting MS information given to SmarcamClub.
In the meanwhile, AAWP have posted an article on the topic, as they've received the same information from Microsoft :
'Force HDR' coming soon to Windows 10 Camera
