It's unclear if this applies to third-party email addresses configured to use smtp.gmail.com as the outbound SMTP server or if it only applies to third-party email addresses using actual external 3rd party SMTP servers.
I'm interested in this as well. I would assume all of them from the announcement. I.e. they are removing that functionality altogether from regular Gmail (not Workspace).
