The device-less mount I described is a feature of *JFFS2*. It does not
depend on if there is UBI or not.

You are just trying to do an incorrect thing.

It is similar to LVM - you feed hard drives to LVM, then create LVM
volumes, then mount those LVM volumes, not the hard drives. Similar in
case of UBI. You feed mtd3 to UBI, then you create UBI volumes which are
also accessible as emulated MTD devices, and you mount _those_ MTD
devices.
