Cordless is still using an outdated API, which is a red flag, Ripcord is up-to-date and uses the same endpoint as Discord's own client, so it's less of a risk getting banned
I'm the contributor regarding the VTxxx stuff. I agree with your idea, considering the fact that Discord uses Electron which is just sandboxed Chromium, which uses quite a lot of RAM. For a product marketed towards gamers (or at least was), this is not good. What a shitty reality. I wish I can go back to TS3 and its Qt client... oh well, we have Mumble anyway.
