Face normals do not seem to be as widely supported as vertex and corner
normals, so meshes with the 'FACE' .normals_domain are now exported as
corner normals instead.

See blender/blender#117470.

I can't think of any reasons to export face normals that would warrant adding an option to the exporter, so I think it will be best to leave exported normals as corner/vertex for now.

Vertex normals are not as common to find in .fbx files as corner normals, but I wouldn't say they are uncommon. Both vertex and corner normals are present in much example code in the FBX SDK, so support for vertex normals is likely pretty good.
