If main sequence stars were candles, supernova would be a nuclear bomb. Elements heavier than iron are only produced in events that are so energetic, the luminosity can exceed that of the entire galaxy they are in. What was a star becomes a neutron star or black hole afrer the supernova. Main sequence stars do not produce heavy elements until they die.
So if you want to say that radionucleotides come from stars, I won’t play semantics police, but that is reductive to the point of missing out on how incredibly unique supernovae are as a stellar phenomenon.
