I would stay as close to the source as possible. MIT and GPL-2.0 are
compatible, so there is no problem on the project level, and I see no
reason to handle this on the level of individual files.

GPL-2.0+ is the old-style identifier, which is deprecated by SPDX (see
https://spdx.org/licenses/ at the bottom).  I think we should also use
new-style GPL-2.0-or-later or GPL-2.0-only here.

The rest looks okay. Thanks for picking this up!
