I don't recall there being any consensus on using "gb:national" in place of the more detailed variants, and I certainly don't think there has been any discussion of or agreement for a mass mechanical edit to change existing values. So if that's what's happened (I haven't looked) I think the changes should reverted pending the outcome of that discussion. >From a data point of view, I'd very much prefer to see the more specific values (e.g. nsl_single, nsl_dual, and motorway) used. The type of speed limit is important if you're a non-car where different defaults can apply. While you'll usually be able to tell what sort of speed limit it is from the highway=* and maxspeed=* values, that's additional work on the part of data consumers, and I think it would be better for us to store the redundant information to help them out. Doing so also provides an additional consistency check that will help us detect possible mistakes in our mapping, and will make it easier for us to accurately apply bulk changes to speed limits should the national limits every be changed.
