Marek,

Why I've asked about the rule from community, which forbids this ^^^ changes:

If there is a change to the OSM, which reverts something, which is not forbidden, and removes information about smoothness, removes check_date tags, removes objects which are exist in the real world but were absent in OSM, adds object which is absent in the real world, adds wrong information about pedestrian access (maybe it is even dangerous for people's health) — is it okay to call such a change "vandalism"?
