When testing new versions I often perform local mock or scratch builds. I don't necessarily upload the sources or commit them until I believe a build on koji is likely to succeed.
fedpkg needlessly downloads the existing source even though it's not referenced in the updated spec file. For small projects this is just a nuisance (more to clean up later) bug with large projects this can eat up data when done frequently.
I belive this has already been added:
$ fedpkg sources Not downloading unused test-sources-2023-01-04.tar.gz
Yes thank you!
