Come to think of it, OSM traces include timestamps and elevation for each recorded point, plus maybe other data from the uploaded GPX file. Maybe someone will create a Strava-style visualizer that serves HTML, SVGs or PNGs from trace IDs with a map, speed and elevation profile for easy sharing. Imagine your trace is https://www.openstreetmap.org/user/hagu/traces/11959920 and you change openstreetmap.org with perhaps openstreetmap-traceview.org and get a nice sharable overview that also has a PNG for preview on socials. Maybe even a page with a list of activities by user including kilometer stats by month, mode of transport etc.
