What does 2.0 mean? There is no such version of the GPL, and with Gentoo versioning rules, 2 is not equal to 2.0. Another funny thing is that they first introduced a "+" operator, but then decided not to use it for the GPL family, but append "-or-later" instead. (And IIUC, "GPL-2.0-only+" is valid in their scheme and equivalent to "GPL-2.0-or-later".)
