I can't believe grown engineers are afraid of a dot.

I find that more of a reason to do a change than to leave well
enough alone. What's gonna happen when all of the current generation (the
writers of the scripts) retire and close the door on their careers?
How will the Internet live on?
Shouldn't a technical beast be able to thrive on technical changes?
But that question isn't germane to the issue at hand.

Fair enough - my answer is it provides the same as the dotted
quad for IP, it makes it easier for human to human conveyance.
It also makes the transition from 2 byte to 4 byte more obvious
in the interim.

The IETF "really" doesn't "want to create" anything. The IETF is
just a forum where folks can gather to discuss an issue like this.
(Pardon my second non-germane comment on this thread.)

For the same reason - to distinguish the boundaries between what
the old engineers know from what the future young engineers will
take for granted. The dot would outlast the old engineers just
as the dotted quad persists into the CIDR age.
"Why on earth?" Because there aren't [m]any IP addresses on the moon.
