wheelchair-routing is a difficult, unsolved problem IMHO. Yes you can use a profile in Graphhopper and the Heidelberg University did a large project as well.

When talking with wheelchair users I learnt that they often improvise on the routes they take, for example crossing the road even without curb-cut because it is quicker for them or trash bins blocking the sidewalk.

We plan to integrate a base layer design like https://www.accessmap.io/ which can help with basic orientation (eg. red-colored streets if they have a steep incline for example).

At the same time it would be great to have very detailed data about sidewalks in general. Apart from OSM I think this is an interesting definition: https://sharedstreets.io/
