FWIW, I agree with both of you.  :-)

Technically, a contribution is not considered “legally significant” if
it is below 15 lines of code or so (info "(maintain) Legally
Significant").

Furthermore, copyright only applies to things that are “inventive”,
which typically means there’s more than one way to do it.  Thus, one
could argue about whether some of our package definitions are
copyrightable at all (in the EU, there’s a “sui generis” database right
though, so it could fall under that, but IANAL.)

Anyway, long story short: I agree with Nicolas that it’s easier to just
always add a copyright line, and it’s better than forgetting to add one.
