One use case I was potentially thinking about was that you have to load
devlink at some point to e.g.: recover your device from an initramfs,
and then you don't use devlink anymore so just you rmmod it and you have
switched to a different filesystem entirely (possibly on the network
that you just helped recover). That sounds like a corner case though so:
