LGTM

Impressive. Is this done via a script and then verified? How is this verified/tested?

[Kleidukos]

@Mikolaj Absolutely, the cabal-dev-scripts project has the gen-spdx and gen-spdx-exc executables to regenerate these lists from the JSON data that is provided. :)

[Mikolaj]

@Kleidukos: and how is this modified code verified/tested?

[Kleidukos]

@Mikolaj I learned the existence of this script yesterday evening, so I can't answer this. Maybe @gbaz has some insight?

[Mikolaj]

@gbaz: any comments? If not, let's merge before it bit-rots. :)

[Mikolaj]

Ready to merge IMHO.

We'll have to remember to add the new licenses to cabal-version 3.8 (Cabal-syntax/src/Distribution/SPDX/LicenseListVersion.hs and doc/file-format-changelog.rst)

[fgaz]

It looks like CabalSpecV3_8 already exists, so this is easily done. @Kleidukos could you open a follow-up pr with the necessary changes to the files I mentioned?

[gbaz]

for the record i have absolutely no insight as to the scripts.
