You did add a very small number foot=no tags, e.g. https://www.openstreetmap.org/way/184658172/history/9

You may also infer the UK mapping community's general attitude to foot=use_sidepath from the fact that there are only 72 instances of that tag in the UK, 10% of which are on nodes (no idea what was intended there).
