Proposal : use sidewalks for bike routes

Hello, I’m new on this forum so I don’t know if I’m at the right place for this post, so sorry if I’m wrong.
I just wanted to make a small proposal in calculating routes for biking.
When you use GraphHopper to do that, it allows you to take some steps with the messsage to get off the bike. I wonder if there was a way to do the same thing, but to use sidewalks (according to the “sidewalk” tag) to take oneway roads in both direction…because it can sometimes really optimize the length of the itinerary.
Thank you in advance.

Oh sorry I didn’t search well. Thank you !
