I don't think we need to worry -- anything semi-permanently installed in the plane (seats, gauges, radios, intercom, etc.) is already included in the published empty weight and moment (which is ammended by an AME [Canada] or IA [U.S.] whenever anything is installed or removed). In a 172 or Cherokee, even the oil is already included in the empty weight. In fact, some things are easily removeable -- most avionics pop out of their trays so that you can bring them in for repair, take them home, etc., without any signoff from an AME/IA. I have also removed and reinstalled VOR and ADF heads, which are a little trickier, but mostly because of the limited working space on the floor under the panel (I needed an AME signoff to reinstall them, but not to take them out). In theory, pilots should ammend the W&B whenever they take anything out temporarily or put it back in, but in practice, the weight is so small and so close to the CG that people don't seem to bother.
