Brings new meaning to the term 'Phantom power supply'
We need a mains switch/breaker to go along with that.

Fun. I sort of doubt whether that has the same benefit as wall warts, namely getting rid of a lot of safety testing agita, but I've never taken a product through UL cert myself.

Right, at 5 watts out a wart will make more sense. At maybe 200 watts, it might be useful.
I did a CE self-certify recently for a customer who wanted the sticker on a box, and declaring that it used external DC (namely not our problem) helped.

I wonder: by how much margin does it pass conducted EMC? Some of their PCB mounted ones (RAC01-XXSC) had disturbingly little margin without adding my own extra filtering, making the compliance testing somewhat a matter of luck, depending on the sign of the small errors in calibration of the gear at the test lab. I guess it doesn't matter so much if your timescale can accomodate more than one attempt at passing, provided you are not selling a sub-assembly to someone else who will blame you if their bigger product doesn't pass first go.
