https://www.khronos.org/registry/webgl/extensions/EXT_texture_norm16/ was recently promoted to community approved, and ANGLE has good support for it across all platforms. WebKit's WebGL implementation should expose it for best portability of higher-end applications.

For reference, EXT_texture_norm16 was exposed in Chromium in https://crbug.com/1000354 - this may help with the browser-side IDL changes. WebKit's current copy of ANGLE doesn't have a Metal implementation of this extension. Ideally this would be implemented upstream in ANGLE first under http://anglebug.com/6547 , and then ANGLE rolled forward into WebKit. A colleague at Esri indicates this is an important extension for GIS applications.
