They’re almost always deployed in controlled environments like DCs - not even enthusiast or prosumers need or benefit from them. The power thing is either an anomaly, misconfiguration, or deliberately designed to avoid heat/cool stresses. Being powered on all the time isn’t always bad - it’s the stress of heating up and down suddenly when power is lost that often causes damage. There was a spate of issues with early (~2010) POE switches where a port would randomly die when they were rebooted. Some of the power components would literally crack and shatter.
