Off-topic: The switching between light background for text and dark background for code is stupid and annoying. Either use dark for both, or light for both (so I can apply my custom inverse shader without hurting my eyes or breaking the reading flow). This back and forth switching is almost as stupid as using a background color with middle lightness, which I've also seen.

This has been irking me for a while, so I decided to randomly whine about it now.

As for the blog content. It's a weird collection of clippy bugs which covers basically the first half of the blog, then a couple of miri bugs and limitations. Then it finally gets to actual rust compiler stuff which just involves cfg_select (a nice to have) and c_variadic support (ffi use-case). So, IMHO, that title is a bit over the top, and it almost does a disservice to a lot of actual good and interesting work that is being done.
