Is it?  Why so?  It appears that the first versions of that file did
not include any license header at all, which means they were
contributed under the project-wide GPLv2+ license.

Only your commit added - 7 years later! - a GPLv2 only license header,
and I really wonder what the base for this change would be?

Which "original v2-only code" are you referring to?

I fail to see where your "v2-only" notion is coming from.
