Not sure there's anything inherently unsafe about outputting the power supply at full capacity.
This is likely just an actual PD controller that always tries to negotiate the maximum power. Nothing wrong with that.
The second link if it's actually outputting max voltage/current over the USB Type-A: that's probably not safe. I don't think any USB Type-A connector is rated for 5 amps. Don't think there should be any issue with the voltage, besides the fact you'll fry any regular USB device if you plug it in...
