Ann, thanks for the other examples to consider. I appreciate your scholarly approach. And your take on it appears to be that these stars are prone to tantrums, so that becomes the more likely explanation.
One reason why massive stars are prone to outbursts is that they are so very often members of binary or multiple systems. Being massive in themselves, and having close encounters with other massive stars - well, that could create both fireworks and hiccups. And maybe bubbles, too.
