MailBox API - Development Roadmap

Will the new MailBox API; along with OAuth/MFA be usable with the Outlook Connector; and ActiveSync clients or Mobile devices? Or any of the CALDav/CardDav functions? I’d love to see OAuth and MFA be usable in more than just Webmail; creation of “App Passwords” to allow for legacy POP/IMAP access; or access to CalDav/WebDav/CardDav/iCal links.
