It’s actually thought to be benificial. The old notion that it’s some remnant from before is considered wrong today, and it seems that different mammals evolved an appendix parallel to each other.
I seem to remember an article saying that the appendix is used by the body to store gut bacteria, as a reserve in case the gut bacteria in the intestines are killed off by disease or something similar.
True, and it seems to also have function in the immune system.
