So it's "-or-later" for the GPL family but "+" for all others?
That doesn't look like a consistent format to me.

Also, what does "GPL-2.0-or-later" mean? There is no version 2.0 of the
GPL, and by version ordering rules (ours, as well as GNU strverscmp(3)),
"2" is less than "2.0". So GPL version 2 is not matched by it.
