I'm going to watch the over the next few days and see whether Mail is writing to any of them other than the main index. If not, I'll do as you suggest and and then delete them. I just hope the next update addresses some of these issues. In the meantime, I continue to explore alternatives; unfortunately, I use several aliases, and none of them handle that quite as elegantly as Mail.app.
