I'm generally opposed to services unnecessarily wanting IDs, content filtering for direct messages from my contacts, unwanted popups (it's already annoying when my friends send me a link to a site I haven't visited from discord before and it "warns" me and you cannot disable this entirely useless popups), and things generally becoming worse.
A lot of these things are normalized already, but requiring IDs is not and I don't want to see it become normalized.
Ultimately, they are free to do what they like (or perhaps being unnecessarily pressured by various govts) and I am free to leave the service.
They're saying there's a very good chance that, in your use case, you still won't be asked to provide ID.
