Mapbox presumably does this now. The issue with the real world is that you do need some high quality truth data to do any decent routing. Different users/vehicles are more or less sensitive to road conditions. If you want to provide an effective micro-mobility routing solution you have to know with certainty where the sidewalks and bike lanes are, how wide they are, how f'ed-up they are and provide directions accordingly. Waiting until 10,000 different transportation agencies decide to fix sidewalks and bike lanes on different schedules and different standards isn't gonna solve issues any time soon.
