This proposal of tagging the allowed left turns will be quite a headache for people who make routers. The biggest problem is that the router needs to recognize that the road is a divided highway (workable but not trivial in the current OSM practice) before it can determine where there are possible left turns.
Don't let that stop you. We need a tag scheme, and need to tag, for roads where the two directions of traffic are divided (separated), indicating the type of division (even just physical or legal), for those roads that are not split into "dual carriageways". The US is full of such roads, too, where routers currently allow a left turn that is physically impossible or unlawful. We need an alternative to splitting such roads into dual carriageways.
