@bortzmeyer@mastodon.gougere.fr @pypi@fosstodon.org Because not all #TLD registries joined the #RDAP fiesta 🙂 ? And in theory even a change of registrant, or maybe even DNS provider (or MX records) should trigger a "emails on this domain are not verified anymore" situation. As it should trigger certificates revocation too, which won't happen (hence shorter lifetimes as a solution).
