This was requirement from udev side.
Initially the "dm-X" device were never intended to be visible in userspace...
Anyway, seems that there is lot of discussion around this problem,
please can we move this generic discussion to more appropriate list?
(dm-devel, lvm-devel or udev/hotplug ?)

I fully agree. Nobody want to display dm-X devices to users.
(and btw df is fixed already upstream to not display these devices and
prefer user friendly names)
But please read this thread first for context...
