SPDX released version 3 of their license list (<https://spdx.org/licenses/>),
which changed the FSF licenses to explicitly end in -only or -or-later
instead of relying on an easy to miss + symbol.

Xerxes is not passing OpentypeSanitizer check per
https://bugzilla.mozilla.org/show_bug.cgi?id=964696 that is why it won't work
