If you type google.com you don't expect FB to replace it to bing.com without telling you. /path and /path/ are two totally different things in the standards, just like /path and /path2. Sure in most cases with and without trailing slash gives the same page; but it's not something you can assume. Same reason why "we don't allow https links" doesn't mean you can just drop the s.
