I think you're overthinking things here: think of copyright as a name
for any text you might want to put at the bottom of the first page.
It's not important what I think, it is important what can be read on the code at a glance.
If I write copyright = "Composed in 2021", then I have to add a comment note above that line as memo for explaining that the copyright field was used for another purpose. Not a clean code, IMHO.
