I believe that's because many power supplies' first step is to rectify the DC into AC, so if you feed in DC directly it "just works".

E.g. bridge less totem-pole designs where rectifying and the active power factor correction stage are fused, would also work unless the firmware gets confused by the lack of input polarity flipping. And yes, that topology can also go into a flyback transformer or pretty much any other unipolar magnetic of an SMPS.
