I opted in this morning. Nothing special.
Outlook/Exchange has expiry and revocation. Expired messages are not deleted, the subject is stuck out. Revocation only works if the message has not been read. Don't know if these work with mobile Exchange accounts, but they certainly don't work with IMAP.
Google is just adding Confidential mode to grab Microsoft customers. It may only be available in G Suite. It is implemented by storing the message on Google and including a link in the email. That means no offline access.
If "do not copy" is implemented in javascript, you can defeat it (restricted sites in IE, developer tools).
