Which is all fine and dandy as long as you never have to interact with those people, but in this case the author would absolutely have to do that. If not directly in their issue tracker (though certainly there), then in every conversation about their project from then on. That would be quite tiring for most people and lead to burnout.

If you don’t think so, I’d be interested in understanding what you see as the principal difference between those statements. To clarify, I was also referring to (internet) strangers.
In sum, why even bother in this case? Just rip it out to a plugin and never think about it again. Now that is pragmatic.
