The dev still has the power to choose the default; the user just has the ability to veto it. That sounds like a massive positive, from the user's perspective.

So? An app isn't meant to hang in a museum and look pretty for the developer.

If the end user thinks it would be better with a different font or larger text or a different background, then they're right.

And realistically once an app ships to the end user the developer has forfeited all control anyway.

Oh how many devs i have encountered over the years with that exact attitude, in particular post iPhone...
