I was curious if we can expect support for draco compression anytime soon within ArcGIS JS API 4.x. I noticed that it started being supported in ArcGIS Online & ArcGIS Pro, but as of 4.15 still seems to be unsupported. I get this console warning when trying to render a draco compressed GLTF:

[esri.views.3d.layers.graphics.Graphics3DSymbolLayer] gltf loader was not able to load unsupported feature. Required extensions: KHR_draco_mesh_compression

This would substantially reduce the browser memory we are using, and load times.

Thanks
