Feature
I'm not sure if OSRM already supports elevation data used from external elevation providers for route calculation. But if so or you're planning this feature in the future:
You maybe you wanna try "Sonny's LiDAR Digital Terrain Models" at https://sonny.4lima.de/ as an alternative within Europe?
The accuracy and resolution of its models' elevations compared to satellite-based surveys like ASTER, ALOS, COPERNICUS or SRTM is significantly better. Especially in wooded areas, steep rocky terrain or narrow valleys. File format (.hgt) and file size stays the same as used in SRTM.
