This extension provided the AMD_compressed_ATC_texture formats to the web. Hardware support has dwindled to near-zero, so the extension has been deprecated/rejected by the WebGL Working Group. Support for this extension has always been small (as it is hardware-dependent), so no existing applications should be relying on its presence.
