Does it make sense to change the type?  Or should we have a new top-level
interface to create and configure discovery subsystems from the start?

If we had e.g.

/sys/kernel/config/nvmet/discovery-subsystems/

we could start that out with a pre-filled well known discovery subsystem
but also allow disabling that for example if we really want.
