That's an argument strongly in favour of ranged specs. A huge number of
packages are licensed under "GPL 2 or later", and currently most ebuilds
incorrectly use LICENSE="GPL-2" for these. Even changing these to
LICENSE="|| ( GPL-2 GPL-3 )" just shifts the problem around a bit. With
CRAN "GPL 2 or later" translates to "GPL (>= 2)", which is a much more
accurate description of a package's license.
