Well the quirk I had in mind was basically that the ‘Mech has the hand/footholds, power/comm connections and gyro programming to directly support BA, just not the modularity that a full Omni has. I could imagine this possibly being on ‘Mechs like the Argus or Thanatos that were originally designed as Omnis before the government declined them, but possibly allowing the BA capacity in order to support the growing BA infantry the AFFS is pushing. But back to the connections, I imagine it almost like a militarized version of the wireless chargers on cellphones nowadays, with possibly some fiber optic jacks for the comm functionality.
