IIRC, Rainer's work on the GC was discussed in the forums at the 
time. The fork-based GC was a SAOC 2018 project, but it wasn't 
actually merged until last fall. [I announced it on the 
blog](https://dlang.org/blog/2021/10/29/dlang-news-september-october-2021-d-2-098-0-openbsd-saoc-dconf-online-swag/) and [in a YouTube video](https://youtu.be/jX9grHMTGAU?t=229).
