If you draw a line on lifespan, I'd say alright, fair enough, like if you're a power user running basically any laptop nowadays. But "Unlikely to be damaged by overheating" isn't a guarantee, and if the user doesn't care simply about whether his CPU will fry itself, it's worth noting a few things, the first of which is the vicious cycle of temperature and energy in semiconductors, which describes the the self-reinforcing cycle of energy lost as heat causing even more energy to be lost as heat, which shouldn't be underestimated. Also, there's the fact that today's CPUs boost algorithms are essentially opportunistic, and they factor power and heat when deciding if and how much to boost the CPU, and temperature doesn't need to reach TjMax for it to decide not to boost, like with the 5800X3D, which refuses to boost PBO to max if temperature goes above 77C.
