Automatisms only are needed in circumstances when one has not the time to think about exposure and focus. Those situations never happen in LF or ULF because the time it takes to set up the frame and the movements is long and, in general, the concept of "focus" with LF is on an entirely different plane (pardon the mediocre pun) and cannot be made automatic. Exposure is a matter of seconds.
If there ever had been a need for an autoexposure LF camera it would certainly exist.
If one has those few seconds at his disposal necessary to establish focus and exposure, manual setting is much less prone to mistakes or unintended results than any automatism.
