This uclass is intended for devices that do not need any features from the

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.
Can you expand this motivation a little? I am not sure why calling
dm_scan_fdt_dev() would be problematic.
In the case of the USB wrappers, there are 2 children nodes: one for
peripheral and one for host. The wrapper binds only one of them.
dm_scan_fdt_dev() would bind both.
Also if you do add a new uclass it should have a sandbox driver and test.
There isn't much to test, except to check that the uclass is present.
The UCLASS itself does not provide any feature.
