In #170 (comment), there was this throwaway note:

Having a last-modified dating to 2017, when in fact the file was changed in 2021 is quite confusing.

I'd personally suggest removing the line, or replacing it with a note to see the git blame or something.

I don't see a code of conduct or a template or anything, so I'm not going to make a PR unless someone indicates they're willing to accept such a change. I'd be willing to make a PR as it would be trivial.
