Yes, from the page I cited it seems that they decided that differentiating with only a '+' character was a bad idea -- the exact thing Micha=C5=82 is suggesting we stop doing. > Release 3.0 replaced previous Identifiers for GNU licenses with more expl= icit Identifiers to reflect the "this version only" or "any later version" = option specific to those licenses. As such, the previously used Identifiers= for those licenses are deprecated as of v3.0.
