I don't think that's true. direct_video can output low frequency: https://mister-devel.github.io/MkDocs_MiSTer/advanced/directvideo/#how-to-use
Direct Video can do 15 kHz but you still have to get it out of the VGA connector and into your JAMMA harness. And the 15 kHz signal the Direct Video outputs isn't amplified correctly for 15 kHz cab monitors. That's why the Kami and other MiSTer JAMMA solutions add an amplifier to the video signals.
