Yep, it is for WebRTC, they are used to create the device id's the browser send to identify the mic and the camera in the enumerateDevices function. It avoids fingerprinting creating different ids per origin, but allows the user to configure a default device per origin. More information here:

I think there is some API in WebsiteDataStoreConfiguration to change the directory but I don't remember if there is a way to change that from the glib API. This is the original commit:
