I don't think it will ever happen, there must be literally millions of embedded links to twitter.com in webpages. They may end up being mirrors of the same data but twitter.com will be around for a long time yet. (Unless Musk really is trying to destroy the company, which is starting to look plausible).
@hoodlem Wow, really that fast? That is not a date, but let's say: 1 July ;P?
Personally, I think due to technical reasons, it might take 2 months from now. Or it will never happen, due to trademark BS. 2 months; date: 27 Sept. 2023.
