Anyway the centralized nature of Revolt Chat makes it no very appealing for me.
I agree with this. I will probably stick with either matrix or xmpp due, to their federated nature, and strong E2EE. Matrix is a better discord replacement, as it has more features, is more standardized, has a better web client, and has "spaces", which are somewhat analogous to discord servers.
Xmpp however, is much more lightweight on both servers and clients than matrix, and it's E2EE works more reliably (none of that "failed to decrypt nonsense), and makes a better E2EE messenger.
