To be honest, I wouldn’t worry about hdyc warnings either, at least not initially.
For example, apparently I am responsible for 19,000 Osmose level 3 warnings (I’m not). Just looking at the first example from that list, this way (added from one source) overlaps with this way (added from another). It’ll likely need an on-site survey to resolve it properly, and it’s good that the Osmose warning exists so that other mappers can see that they perhaps ought to have a look at it.
It would be definitely the wrong thing to do to try and reduce the number of warnings given by Osmose rather than trying to get the mapping correct (matching what actually exists on the ground).
