Some suggestions to recover a lost account without E-Mail

I had been using Discord from 2018,therefore, in feb 2022 i lost access to my Discord account as i deleted my g-mail address due to some personal reasons which made me stuck in a situation in which i can't access my account. Also, As an average social media user, I have some solutions for it -

(1) Verification through Phone Number to get logged in just like in other "social media" applications out there.

(2) Having double e-mail address in one account - one main and the other for recovery in case if the user has lost access to the main.

(3) As we know many of us had linked many other social networking sites to our Discord account, We should also be able to get access to our account from these social networking sites by Discord asking some questions from us. The main issue here is Discord, being an independent organization can't depend on other SNS for data of its users AKA "Privacy".

(4) By linking our account to other social media applications just like we do in many video games like Google, Facebook, Twitter etc. to get logged in.

I know losing a discord account can make some users depressed so i really want Discord to work on this problem. Thank you!
