They could, but it's a mess of a single directory if you do that.
Having /sys/devices/virtual/tty/ as a place for all tty virtual device
is nicer than /sys/devices/virtual/ as a single place for all of them
(mem, network, tty, misc, etc.)


You supposed to use classes for classification, and devices to
represent the tree so that would be /sys/class/tty/...
