SKIP wastes bandwidth

SKIP headers range from 28 to 60 bytes, not including the IP Security
headers (only 4 to 8 bytes).

SKIP trades "zero-message" initialization with manual configuration --
or a few "optional" certificate discovery messages otherwise -- for
continuous bandwidth degradation on every datagram.

The Internet Protocol Security Working Group spent considerable time in
designing the ESP and AH headers to be as small as possible.

Considering that the average TCP payload is 13 bytes, and the average IP
datagram is 124 or so bytes, bloating every datagram by an extra 50% to
200% is unacceptable.
