As bootstrap locks its entire build directory, parallel bootstrapping for anything becomes impossible. This change enables developers to bypass the locking mechanism (with --bypass-bootstrap-lock flag) when it is unnecessary for their specific use case.

I guess "build directory" here feels misleading. We are using this to protect the entire build -- right? In particular, it is not safe to pass this option just because you've already built rustbuild itself.

I'd feel better removing the "directory" phrasing here and in 1-2 other places.

I agree, "its build directory" feels like directory for the bootstrap artifacts rather than compiler/std/tool ones.
