Roman, Your questions are misguided. A larger dev_t is infrastructure. A sand road that is turned into an asphalt road.
Nobody has to use this improved infrastructure. But many uses are conceivable.
Long ago I reserved 2^40 values for dynamically assigned anonymous devices. Convenient, a very small fraction of the available space.
I can imagine that there will be people wanting to take part of the available space for a universal hash of disk serial number or partition label or I don't know what, so that devices are addressable by content instead of path.
A lot of room can be put to many uses.
