Doesn't that EA> seem weird? Err, no? Aside from nnselect and nnvirtual, every article is already in its original group so warping should be a no-op. I added warping early on to nnir simply because nnir was completely ephemeral: that is, no changes made would propagate back to the original article (i.e. if you wanted to tick an article it wouldn't stick if you did so after a search---warping was a hack to deal with that). Now that nnselect does everything a regular backend does, there shouldn't be much use for warping. I never used nnvirtual so I never made changes for it. I see no reason NOT to add a warping for nnvirtual which should be straightforward (as you describe below). But I am curious what the use case is? nnvirtual already does (some) propagation back to the originating groups. (BTW I think the stuff I posted some weeks ago does pretty well at replacing nnvirtual in nnselect. I haven't tested it very much but if it lacks something I can look into it).
