To add more examples, a game I play on my phone got an update that adds controller support on iOS, with controller support on Android expected 6 months down the line.

There are plenty examples to the contrary. It's almost like one of the platforms has the supermajority of phones in most countries, so there are plenty of apps only targeting a single one.

Do you have any examples handy? It'd strengthen your argument a great deal, even if it wasn't the specific example of controller support.
