I suspect the vast majority of these class=highway ways will fall into one of these two categories: 1) The way also has a highway tag 2) There will be a way either directly on top, or running in a vaguely overlapping way, which has highway tags. (quite possibly with a FIXME=previously unwayed segment.. or whatever the tag is). So any automatic script is going to be either unnecessary, or harmful (you'll end up with two roads instead of just one). In "obvious" "deprecation" like this I think you're better off writing a tool to find them, and flag them for people to go have a look at. The real question to ask here is what the "clean-up" is meant to achieve? Especially when the new tag does not really interfere with the old tag, what does forcibly removing the old tag actually get you? Perhaps a cleaner data model, or a smaller planet dump, but only in the extreme case where you actually succeed. And are these worth the instant breakage of tools you have nothing to do with?
