The changelog should propagate to dist-git as the SPDX migration
initiative tracks 'spdx' string in changelogs.

I'm at the SPDX hackfest right now and the guidance I got about the
LICENSE Copyright line was:
1. it's meaningless and a waste of time to polish
2. only the "copyright" word has a meaning
3. the year is meaningless, hence I dropped it
4. the team name & authors is relevant so I updated it to match 100%
   what we have in the source files
