God wants us to call him by his proper name.  Yes, we need to do so reverently but without fear.  but I think that not using this name that is given over 6800 times in the OT is just as much misusing this name as swearing.  Using it “in vain” is just as bad as not using it at all in my opinion.  So Yes, we need to treat it as holy and sacred but not untouchable (unspeakable).  Remember, he revealed this name to us so we can know him better.  So get to know him better through this name Yahweh.
