Russia and China may well be still developing fabs for such node sizes as they catchup.

EDIT ADD https://www.techspot.com/news/94233-russia-plans-manufacture... "Russia plans to manufacture chips locally on a 28 nm node by 2030" currently they are on 90nm

I wonder if it would make sense to keep producing > 28nm with smaller margins in order to make it harder for this competition to catch up and keep a large moat.

If TSMC stops 28+ within a few years, nobody will need it by 2030 with such a huge gap in supply.
