I was actually opted out by default. I opted in, I think it’s a good feature and it seems well implemented as well - your username will not show, only your message. Also only select channels opted in by server admins will show up in searches, which is probably the best way to go about it. I don’t exactly care for everyone’s “general” chats to become indexable, but I’d like not to open Discord just to look up some techy stuff.
