The Bris Kehuna (ma’areches kuf) disagrees with the Chayei Adam and says it’s a joyous occasion and says one should tell everyone. My rav says that there is no makor for the Chayei Adam, and that aderaba, from the Sefer Chasidim (807) it is mashma like the Bris Kehuna, because he discusses the halacha of whether one who disrupted some people from chazaras hashatz to tell them about a rainbow for them to make a bracha on did the right thing, and he doesn’t mention anything about not telling people about rainbows.
