Agree, but we do try to create statistics and try to derive quality
statements from those tags (yes, empirical software engineering black
Hence, I am in favor of suggesting to rewrite those tags that really
do not add anything at all. E.g., Suggestions-by: vs. Suggested-by, or
Coauthored-by vs. Co-developed-by.

Anyone can ignore checkpatch; so it is not a constraint unless
enforced by subsystem maintainers.

I think we do not want to take the humor and fun away from patches.

So let us not suggest deleting the humorous and celebrating ones.

Maybe a patch reduced to the very obvious synonyms helps newcomers or
people with lousy memory to be reminded that it is called
"Co-developed-by:" not "Co-authored-by".
