What is the difference between downloading the rustc sysroot from this GitHub project's release and the official Rust release? If it's just a difference in nightly or specific versions, can the RUSTOWL_SYSROOTS environment variable be added back?
Because nix under this mandatory download of the latter version are buggy, need to compile and install when the full resolution of dependencies.
I added the following code to fix the bug, using the rust sysroot from the rust-toolchain.toml (nightly-2025-04-08)
version of this project.

I don't see any difference myself, hence the question above.
