imap and end of basic auth in Google an Office365

[Jan Vávra <vavra@xxxxxx>]

Hello,
 do I understand correctly that there should be something implemented 
in the php imap module to support OAuth2 authentication scheme?
Resources:
https://wiki.php.net/todo/ext/imap/xoauth2
https://bugs.php.net/bug.php?id=64039

For me there are currently alternatices:
1. Use a http rest api of these services to recieve and eml source of email
2. Buy a Chilkat library, there is an example: 
https://www.example-code.com/phpExt/gmail_imap_login_oauth2.asp

Are there any other alternatives?

Jan.
