Evergreen and later chips support S8, but there are limitations: if you want to bind a separate depth buffer to it, it must have the same tiling parameters except for the tile split (that's the only one that can be different) and HTILE must be disabled. Not really worth implementing.
S8 without a depth buffer can be supported easily. Just set the depth format to "invalid".
