It may not be smartest idea ever, but for clufter, I have an extra file added as a source (fix-jing-simplified-rng.xsl):
fix-jing-simplified-rng.xsl
https://pkgs.fedoraproject.org/cgit/rpms/clufter.git/tree/sources?id=62e5f18870724aedc9b17d3c5a106ff114788c88#n1
and occasionally, I am updating that file. Simple logic concludes sources file should not, under any circumstance, contain two files of the same name (regardless of the hash) as the SRPM cannot contain such two files at the same time. Therefore, I would expect fedpkg upload fix-jing-simplified-rng.xsl when such a file is already tracked in sources to drop original entry/-ies first and emit a warning about that.
