I've migrated the toolchain autoupdate scripts here, I just need a little more time to do the explorer side (which I need to check performance, that may require multithreading as we do in the current script). However, this felt substantial enough to share and it means I can handle autoupdate in more of the toolchain, including preparatory work for autoupdate on multi-file tests. Once explorer is done I'll remove the old script.
