Not law yet
This is the HMRC report on its intentions for the Finance Bill. It still has to pass Parliament, and the report from the Lords call for written evidence that closed on the 25th Feb. is still not in. So there's still a slim chance things might change a bit for the better. If not, we're stuffed of course but as IR35 is based on the fiction of a special class of company that has no legal existence, there's also always the possibility of a judicial review if someone can raise the dosh.
