OAuth SMTP support

I've just spent several hours trying to set up Vaultwarden SMTP to work with my Microsoft 365 service. Tbf it was mostly due to Microsoft's settings being spread across many websites, docs etc., but the main takeaway is that they disable basic authentication methods by default and consider them obsolete. I've read that Google does the same and I have to say that I would also feel better without storing my password in plain text in an .env file.

I checked the meta feature issue and I did not see supporting XOauth2 auth method being listed, neither did I see any doc page in the wiki on how to use it. Is this feature planned?
