I understand that for many if not even most situations, anything you add 
to the content you probably also want to add to the excerpt. I get that.

My issue is that it's impossible to not do it this way. It would be 
great if there were a filter for "after_the_content" or 
"post_the_content" or something like that allowing you to just filter 
the content and leave the excerpt alone.

Having wp_trim_excerpt() filter "get_the_content" instead of 
"the_content" makes more sense to me, though I understand it's 
impossible to change it at this point.
