IIRC their Rust kernel hit some size barrier (for the bootloader?). The author tried to build a smaller standard lib to overcome this, which was a bit of work.
I didn't see that from skimming; if it was bootloaders, well, they have a max size of 512 bytes (on x86) so virtually all bootloaders load in stages, with a tiny bootloader that loads the "real" bootloader.
