Unfortunately we still have work to do there. We have dabbled in a separate map style, but it's really difficult to get any roadnames to show up when you start increasing font sizes in map styles. It's a sort of pick-your-poison - big maps where you can see the roads with almost no road names, or maps with smaller details with road names. The app itself should mostly scale well with increased system font sizes, but we are still carving out a couple of webviews in the app which have funky behavior. I do like to joke that with our average staff age passing 40 in the next year or two, we'll solve all readability issues....
