The combined temperature/pressure relief valve ensures that you don't generate steam and hence only have to contend with (generally) a leak of hot water when the unit fails.

"The Code Committee does not rule on whether a component shall or shall not be constructed to the provisions of the Code. The Scope of each Section has been established to identify the components and parameters considered by the Committee in formulating the Code rules."
It's the local legislation that tells you which code to use. Your insurance company's fine print may also have a say. But if anything applies, it would normally be Section IV, not VIII.
