My original idea was to convert the OSM database from 2D to 3D. Each node would then have not only latitude and longitude, but also altitude. I would populate the database with an initial guess of this altitude based on SRTM. Everyone would be free to change them, just like with latitudes and longitudes. The main advantage is that altitude would be nothing fundamentally different, which is very intuitive for me. You have made the disadvantages quite clear, so I will change my proposal. So no 3D nodes (and no interpolation). I'll get back to you quickly with the new version.
