I was aware of GPL-2.0+ being deprecated, but not GPL-2.0. And indeed
SPDX now uses GPL-2.0-or-later (instead of GPL-2.0+) and GPL-2.0-only
(instead of GPL-2.0).

Ideally yes, to follow SPDX. However, there are a few gotchas:

 - The number of packages that need to be changed (though that's easily
   doable with sed)

 - The potential backward compatibility breakage. If people have
   scripts/tools that parses our manifest.csv and interpret the license
   values, the renaming might break for them.

But maybe these are not that important, and sticking to SPDX is mort
important ?

Anyway, that's a separate discussion from Peter's patch. Peter's patch
is fine as-is, as it matches the current practice in Buildroot.
