Why the need for comments in server-side includes?

Hi, I sometimes create a page and use a portion of that page (header, footer etc) to create an include-page. No problems. I might then change the name of the original file or delete it altogether but I’ve noticed the comments on top of the include file still refer to the original page it was taken from.

What’s the reason for having comments in the include page that mentions the original file and the dependencies (bootstrap, fontawesome, jquery etc)? Can they be removed or they helpful in some way?
