This paragraph is not really understandable for Joe Developer.

  copyleft-next-0.3.1 is explicitly compatible with GPLv2 (or later) and
  can therefore be used for kernel code. Though the best and recommended
  practice is to express this in the SPDX license identifier by
  licensing the code under both licenses expressed by the OR operator.

Hmm?

Please don't propagate the GPL-2.0 and GPL-2.0+ tags. They are
outdated (still valid) in the SPDX spec, which reminds me that I should
update the relevant documentation...

Thanks,
