Non those are USB-PD power supplies that increase voltage up to 20V in order to deliver more power. No USB standard that I'm aware of offers 5A at 5V.
As far as heat goes, these devices already need heatsinks and case fans, so the difference seems negligible.
Also, good luck using a Pi5 any further than 3ft from a wall outlet unless you want to rig up your own power supply using some 14/2 Romex with a USB C connector soldered to the end.
Pi 4 and below don't require active cooling. I want to keep it that way.
Again, I offer no defense of Pi5. I don't use it and don't recommend it.
