Re: Gmail OAuth2 in git send-email

Hi,

For most email providers, adding following .gitconfig is enough to
seamlessly use git send-email:

quoted

           [sendemail]
                   smtpEncryption = tls
                   smtpServer = <server>
                   smtpUser = <email>
                   smtpServerPort = 587

But for users that use Gmail (like me), we must either enable 2FA and
generate app-specific password for use with git send-email, or enable
less-secure app access. That's because Gmail prefers authenticating with
OAuth2, but git send-email use plain text authentication instead.

I personally prefer the latter because I know that I enabled less-secure
app access only for duration of sending patches with git send-email
(that is, I switched the trigger when I run git send-email).

We wonder whether git send-email can support Gmail OAuth2 so that we can
seamlessly send patches without having to choose either action. But
however, we have to create a GCP project [1] first in order to enable
Gmail API. This can be overkill for some folks, but unfortunately that's
the only way.

If we want to enable support for Gmail OAuth2, should we hands-off API
configuration to git send-email users, or should we configure it on
behalf of them? Note that when we go the former approach, some Gmail
users simply can't afford GCP pricing for whatever reason (even don't
have any of required payment methods), whereas the latter approach we
must cover that cost (and Software Freedom Conservancy can raise funds
needed for it or git.git developers can pay it).

I met the same question as you before. [1] (write by chinese)
We need cumbersome operations to allow gmail to agree to use git send-email.
I also want to know if send-email can be made more convenient
(to reduce some configuration problems with gmail).
