Explicitly tagging oneway on links is preferable for obvious reasons,
but you need to be careful with must, which is wrong for two reasons.
- The wiki can document, but not set out requirements, as people can
ignore the current state of the wiki.
- Your next sentence discusses the lack of oneway
- There is not a concept of formal validity, so must doesn't apply
- Data consumers will make their own decisions
Tools to help enforcing the obligatory usage:
[...]
- No routing over undefined oneways
The chances of anyone implementing this in their routing engine are
approximately zero.
