Those statements aren't from the certification, they are Title 47 FCC rules! You are wrong in your thinking. I have a friend who works for a TCB company. They issue certifications for compliance with FCC regulations. For marine VHF's, they only do the testing measurements as required by part 80 rules, which I indicated before. As long as it meets those requirements, it passes certification. They don't care what a person might be able to do with their radio. Your the one that is misinformed and missing the point.

Added: The radio must also comply with part 15 subpart B, unintentional radiators, and rules regarding exposure of humans to RF fields.

The certification is all about conducted and radiated emissions, thats it. For everything else about the radio, it's up to the manufacturer to be within the rules. To be sure that the conducted and radiated emissions are within spec's, a third party (other than the manufacturer) must do the testing for FCC certification.

If Icom started providing their radio's with the expanded channels already available in the U.S., they would be in trouble with the FCC but that isn't in the certification. It has nothing to do with that. Certification is only about conducted and radiated emissions.

Sorry, I disagree fairbanks.

Again, your confusing what they have time and resources to test (the important things they actually care about) with what they are actually certifying. And your example with Icom is a good one. Icom failed a certification just a few years ago, because the radio was too easily modified. They had to lock the transceiver down and re-design some of the radio's software in a hurry. That radio ended up having some issues with the software. I do not know for sure, but I'd bet you the software problems were due to the last minute software changes to lock down the radio. They were not tested properly and we all ended up with a uncharacteristic buggy Icom model that was quickly discontinued and replaced. Bet ya can guess what model!!
