Oh sorry, I didn't realize the paragraph you posted was a suggestion, I
thought it was the one you were indicating needed further enhancement!

I'll just take yours then.

Sorry I hadn't had my coffee yet so I should only list:

SPDX-License-Identifier: GPL-2.0-only OR copyleft-next 0.3.1
SPDX-License-Identifier: GPL-2.0-or-later OR copyleft-next-0.3.1
