Maybe the spec allows that pairing (5V@5A) to exist, but it's not implemented in any power supply! Total wattage is irrelevant if the RP5 only accepts 5V. Feel free to link to one if one exists. For sure virtually no PD power supplies support it.
Example: https://www.amazon.com/AmazonBasics-One-Port-Charger-Laptops...
Specs: PD 3.0 (USB-C Port): 5V ⎓ 3A / 9V ⎓ 3A / 12V ⎓ 3A / 15V ⎓ 3A /20V ⎓ 3.25A (Up to 65W)
There are tons and tons of examples like this.
Example: https://www.anker.com/products/a2341
From what I can tell this is a top of the line Anker GaN charger which can produce 140W. However, if you look in the manual: 5.0V 3.0A / 9.0V 3.0A / 15.0V 3.0A / 20.0V 5.0A / 28.0V 5.0A (140.0W Max)
The only power supply I have seen that can do this rediculous 5A at 5V is the one being released for the RP5, https://www.sparkfun.com/products/23584 You can see from the picture it actually outputs a nonstandard 5.1V@5A, suggesting that the voltage drop due to the cable actually causes problems powering the RP5 so they built a 'hot' power supply to try to correct for it. This seems like a pretty big design flaw, why not just design the RP5 so it can negotiate a higher voltage on PD? It looks like it has room for a couple mosfets to implement this.
