I added the warning based on an observation that it has no effect on members of the extension, but didn't validate whether it has some subtle effect on other symbols, such as those for conformances declared with that extension. To reduce confusion, it's better to not warn until it's safe enough to remove uses of it on extensions in the stdlib.
