I am planning on adding this information to wiki in near future. Note that it afffects also highway=path - in that case some/many people are convinced that there is some kind of difference of implied quality between highway=path and highway=footway.
highway=path wiki page already contains information that highway=path "may have any type of surface" 2015-08-12 10:56 GMT+02:00 Mateusz Konieczny <matkoni...@gmail.com>: > What is below is supposed to document existing consensus rather than > introduce new rule.
