I'm not any authority here, but I'd say, there's no need for a Reddit-moment to ban it entirely.
Though it wouldn't bother me either.
Directly linked single text posts are still publicly accessible last I checked, but it's a microblogging platform littered with spam.
HN submissions are usually long-form content, so it's rare to see X links anyway.
And comments obey the voting system, so who cares whether people link to X, LinkedIn, Facebook or whatever else.
Banning X in comments would require to ban the others as well, and I think the mods and users can handle by themselves what is relevant in that case.
And in case an X submission is genuinely interesting, it won't be hard to access or infer the content from the comments or other sources.
There are, at minimum, tens of Twitter links that I see daily which make it to the first couple of pages of the site. A lot of them are AI-related content, which seems to be popular there.

I don’t want to have to do this. I think we should just disallow Twitter links for posts.

There don’t appear to be workarounds for Twitter anymore.
