I think highway=motorway_link is also implied one-way. Are there any others? > There is also the occurence of oneway=-1 in case someone reverses the > direction of a way.

Should you get a warning "oneway street can not > be reversed"? oneway=-1 now triggers a validation warning in JOSM. I have yet to see a case where oneway=-1 is truly needed.
