As per this statement on twitter's developer website (https://developer.twitter.com/en/docs/twitter-api/getting-started/about-twitter-api):

If you were approved for a developer account before November 15th, 2021, you were automatically converted to Elevated access. This means that your existing Apps can continue to be used to make requests to standard v1.1, premium v1.1, and enterprise endpoints, and that all of your user Access Tokens are still valid.

If you would like to start using v2 endpoints, you will need to attach an App to a Project and use the credentials from that App when making requests to v2 endpoints.

New users are locked in to using oauth2 unless they apply for elevated access, which puts you on a wait list. This conflicts with the existing oauth1 implementation for twitter and I feel that the best way to go forward is to add an oauth2 method for it along with oauth1 so that things don't break for existing users, but allow new users the ability to use twitter easily.

It looks like @nbys was the one who did this pr for adding oauth1 implementation - how easy would it be to add in oauth2? I'm not super familiar with go but I could probably take a stab at it myself, I'm just not sure how to handle the whole "allow both oauth1 and oauth2" debacle.
