Sensor Minimum distance of 0 resetting

I saw it discussed and mentioned before so I do not know if this meant to be a bug or feature but currently whenever I interact with a sensor and change multiple ranges of that sensor to 0 it works. In this case I set all the distances except forwards to 0. this allowed me to create long laser like pillars out of the sensors which would be very interesting for an obstacle course build. They work perfectly as intended and there are no problems with how they work as they only occupy the center 0.5m by 0.5 m of a large block. However the problem shows up when I log in and out and all the distances set to 0 reset as 1.This means that they instead of occupying the center 0.5 now occupy the whole large block.

I would like some clarification as to wherever you are meant to have 0 in range for these sensors. It is a cool current feature at this moment and I hope it was intended, but in the case that it was unintended I would like confirmation as it would become annoying to constantly reset my sensors to 0 if it would later be patched out due to it being unintended. Also I'll be monitoring the report if anything is unclear.

apologies for the work
