Thanks for pointing to my thread! (and Cc'ing Richard of course ...)

If we continue on the conversion, I definitely agree with your latter
option (as I have done there).

In that case, IMO, err to the safe side and assume the most restrictive
(GPL-2.0-only).

Just add the SPDX tag...

Above case is wording variation (for which we conclude that only license
boilerplate with exact wording can be replaced by the tag).

Dunno.

Thanks.
