That looks fine.

I wonder why we have this comment:
  +# aoe block devices
  +SUBSYSTEM=="aoe", KERNEL=="etherd*",    NAME="%k", GROUP="disk"

They can not be block devices if they have SUBSYSTEM=="aoe". Do the
etherd* devices belong into the subdir or not?

We have:
  SUBSYSTEM=="aoe", NAME="etherd/%k", GROUP="disk"
in the current default rules.

I guess doing:
  # ATA over Ethernet
  SUBSYSTEM=="aoe", NAME="etherd/%k", GROUP="disk", MODE="0220"
  SUBSYSTEM=="aoe", KERNEL=="err", MODE="0440"
would be all we need.
