I noticed when reviewing my server logs that the comments feeds for individual posts were receiving hits. This is undesirable since the only “comments” we have are pingbacks and webmentions. I wanted to remove the comments feeds from the head. I found a solution in a 2018 Stack Overflow post combined with an addendum from another user. I added the following code to the child theme functions.php both here and on The New Leaf Journal:

add_filter('feed_links_show_comments_feed', function() {
return false;
});

(PS: I am not a WordPress developer. Please do your own research and double check your work before messing with your functions.php, but it seems to be working here. If someone has a better solution, do tell.)
