Poke.
I'm no sure if it's safe to add a new data point, but I'd love to know
the answer to this question. Alternatively we could use EventLogging
on the server side to log people that disable images (as well as those
that opt in and out of beta). I think it's a useful component to have
on mobile especially for the Zero case but if we can avoid using it in
mobile web I think this is a good idea.

I created a story
https://wikimedia.mingle.thoughtworks.com/projects/mobile/cards/1757
in the hope we might explore this.
