you are right, i will take out those rules where xybot is just guessing
the optimal values and ask the maintainers of
http://tools.geofabrik.de/osmi/ or
http://keepright.ipax.at/report_map.php to add them to their validation
tools so a human brain can set them to the correct value.

no, such changes are prohibited in the algorithm.

i think this would result in a massive spamming of the osm users and i
don't think that the messaging infrastructure of osm is able to handle that.
