This uclass is intended for devices that do not need any features from the uclass, including binding children. This will typically be used by devices that are used to bind child devices but do not use dm_scan_fdt_dev() to do it. That is for example the case of several USB wrappers that have 2 child devices (1 for device and 1 for host) but bind only one at a any given time.
