We are all so different, I love getting the selvedge ends for a number of reasons and I am annoyed when they are cut off! I like knowing the direction of the grain, I love any pre-printed info, and sometimes use a sharpie to write other info in the selvedge myself.
Now, I do throw tantrums when I can't get 40" of usable fabric out of a full width. I found out way back around Y2K when I did a lot of 10" square swapping that you can't even depend on that, some manufacturers particularly had huge advertisements of their brand woven into the yardage.
So short yardage, yeah that bothers me and I can understand your concern.
PS: I was also confused if we were talking selvedges or the wrinkled up diagonal junk at the end of the bolt.
