BUR #3195 has been approved by @evazion.
create implication no_entry_sign -> road_sign
create implication stop_sign -> road_sign
remove implication stop_sign -> sign
Looking at stop_sign -road_sign they all seem to be road signs, and I can't imagine any situation where a road sign would also not be a street sign (even when drawn in-world) in the same way we treat other stylized objects.
EDIT: The bulk update request #3195 (forum #170702) has been approved by @evazion.
