No need for a change as it is possible to simply add your new tags

+1

both might be introduced with the "lanes:" tagging system. At least 2.
makes sense. If it is only one lane in opposite direction you usually do
not need an additional ":lanes" in the keys.

1. should be oneway=yes and oneway:psv=no
2. both tags are ok but deleting is not needed.
