The problem here is that a power supply offering 5V 5A is compliant, but a device requiring a 5V 5A source is not.
If a device needs 25W it is required to accept 9V 2.8A, if it wants to be PD compliant. This is precisely because 5V 5A is optional for a 25W source, so a device cannot rely on it being present.
