I don't think the Dictionary discusses this. But NuVoc does, though it's a small point:

My preference for feature removal starts with making the feature optional. Once you can turn it off, it's relatively easy to test for what that breaks. Once most of the breakage is fixed, you can release with it turned off by default. (The migration from x./y. to x/y for verb parameters skipped directly to "turned off by default" which I think was a mistake. But that's old news now.) That said - do you happen to know where the dictionary documents that 2 :'u,v' and 2 :'x,y' behave the same? Thanks,
