What are the odds the notification functionality was only tested to work with Apple's overpriced first party accessories like 79$ USB cables, and will have countless issues and edge cases with third party accessories?
The notification is hardware based; the manufacturer of a USB keyboard or mouse won’t matter.
If you plug a hard drive into the slow USB port, macOS will let you know.
There have been thousands of different USB devices plugged into Macs since they adopted it in 1998; I doubt there’s going to be problems now.
