The DSC receiver inside it uses a SEPARATE ANTENNA and has a SEPARATE
SO-239 antenna jack on the back. I guess Icom thinks I have it
installed aboard a Navy destroyer where there are lots of antennas to
connect it to.

How about it's because the radio can be used as part of a required GMDSS
installation on other than toy boats and the law requires a separate
receiver.

Icom thinks that the people installing the radio know what it is and
will install the radio in compliance with the laws regulating that
application.
