I dunno about that; suppose dozer completes its goal, and 1 year later you want to audit the bootstrap chain. Latest Rust probably won't be able to be compiled by it, so you now need to audit what, 6 months of changes to the Rust language? How many months is short enough to handle? If dozer _does_ keep getting maintained, the situation isn't exactly better either: you instead have to audit the work dozer did to support those 6 months of Rust changes.
