As noted it could only deal with a subset of cases, but I expect it to be a significant subset.

There doesn't seem to be much interest, so I'm not perusing it at this time.

I think converting exit_to to destination would be hard to do anyway because exit_to is added to the motorway_junction node, whereas destination is on a way. That could get ugly really fast, don't you think?
