It's made up but does provide rough tiers within a product generation. Also, modern CPUs and GPUs pretty effectively throttle to the capacity of their cooling solution. I would not necessarily recommend it, but you could probably get by without any issue slapping a solution that reliably dissipates 65W of heat on any Ryzen, and have a stable computer. It would just happen to run up to its thermal limit regularly and clock down. If you actually want a lower power/heat setup, you can undervolt and underclock the CPU and not worry about bouncing off the thermal limits.
