Be aware that size of /home depends on what for computer is used.

I don't have much of multimedia files, but I do have virtual drives (for 
virtual machines in VirtualBox and QEMU) that take few GB each (currently 8) 
so my /home is still too small, and right now I'm using extra 40 GB partition 
that was initially meant to be archive. So satisfying total for my use case 
would be some 60 to 70 GB.

It is not separate. 
It is just udev subsystem entry in /etc/mtab. You can run:
  cat /etc/mtab
to see that and few more. Here is output of mine /etc/mtab:
  /dev/sda6 / reiserfs rw,acl,user_xattr 0 0
  proc /proc proc rw 0 0
  sysfs /sys sysfs rw 0 0
  debugfs /sys/kernel/debug debugfs rw 0 0
  udev /dev tmpfs rw 0 0
  devpts /dev/pts devpts rw,mode=0620,gid=5 0 0
  /dev/sda7 /home ext3 rw 0 0
  securityfs /sys/kernel/security securityfs rw 0 0

I have no idea why command 'df' picked udev. 
Maybe it uses some portion of /dev directory, so it really exists on hard 
disk, while other mounts without slash in front of them, like proc, sysfs, 
debugfs, securityfs exist only in RAM. 

To answer this without preceeding 'maybe' we would need some kernel developer 
to appear in this thread :-)
