Prerequisite: gfx-rs/naga#2195.

Metal supports this.

DX12 optionally supports this (see gpuweb/gpuweb#3640 (comment)).
DX11 doesn't support this.
There is a possible workaround that we can implement if we want (see gpuweb/gpuweb#3640 (comment)).

Vulkan optionally supports this if the format supports STORAGE_WRITE_WITHOUT_FORMAT_BIT (see KhronosGroup/Vulkan-Docs#2027 (comment)).
