is there a need for class A addresses?

These few messages on GE's network address has triggered some thoughts
I have been holding since the Annapolis IETF meeting, basicly:

Is there a need for class A addresses?

I can think of two possible uses of such an address:

1) A very large comm subnet - with 2^24 hosts.
(Does such a network exist? Will future telephones be IP hosts?)

2) Subnetting, say used by an organization with 255 class B networks.
(Would such an organization exist? Could the gateways front-ending the
subnetted network be able to handle the load?)

Your comments on the above will be appreciated.
