IMO it’s less about the voltage and more about the wattage. A modern PoE spec supporting wattages ~100W is more than enough to start a fire. Currently there is a gap in the electric code (NFPA70) as it doesn’t really address this risk in the (vague) section on low voltage wiring. But building codes are written in blood. I’m sure it’s just a matter of time till some PoE cable starts a fire and then the code will get amended.
