A little, but the adapter as such is never exposed in those APIs, just
its index. For cases where it matters (e.g. CheckDeviceFormat()) you
also get a device type parameter.

Exposing real wined3d adapters to the client libraries may not be a
bad idea, but it's not required here. You could use adapter_idx and
device_type together to pick an appropriate adapter to create the
device with.
