The reason for NOT recommending only 2A on either board is that spikes (particularly at bootup) and peripherals require more; dongles of all types, gpio(s), active cooling, etc.
The recommended PSU is NOT for the board only (per se), the recommended PSU is for the normal use case(s) for the board including loading, peripherals, and other current losses including but not limited to gpio(s) , fans , usb receivers , etc.
And another thing; as most of us know, the SoC is not a static entity; faster clock = more current, more cores active = more current, etc. You never pic a PSU based on zero load and idle ! You choose a PSU based on expectations across a range of use case scenarios, including buffers for spikes and extremes.
