Working on my API layer tool and I think I'm hitting "spec doesn't define either way" behavior, but I'm not certain:

If I set XR_ENABLE_API_LAYERS=XR_LAYER_this_layer_does_not_exist in my environment (to attempt to enable an invalid explicit layer)

xrCreateInstance() fails with XR_ERROR_API_LAYER_NOT_PRESENT - this seems correct
xrEnumerateApiLayerProperties without an instance succeeds - this feels wrong, but I'm not finding a clear definition of correct behavior here
