At this point it's too early to even worry about correctness, it doesn't work yet.

But the years of work put into the existing project to make it robust don't mean the exact same years have to be spent on the reimplementation:

- there's been work spent on discovering the right architecture and evolving the db format. A new impl can copy the end result.

- hard lessons have been learned about dealing with bad disks, filesystems, fsync, flaky locks, etc. A new impl can learn from the solutions without having to rediscover them the hard way.

- C projects spend some time on compatibility with C compilers, OSes, and tweaking build scripts, which are relatively easy in Rust.

Testing will need a clever solution. Maybe they'll buy access to the official test suite? Maybe they'll use the original SQLite to fuzz and compare results?
