You would think so, as I did, but the idea seems perfectly fine if the coil is wound on a form a little smaller than needed for the cap so it grips. I have made the connectors from beryllium copper sheet/spring copper, though they don't seem to have any advantage, I have also seen the idea used with PL509's for PA stages in home brew transmitters, also without issue.
