My hope is that a lot of the difficulty in getting reproducible builds is caused by outdated libraries and techniques. For example, assuming that your code is in /usr/bin or /usr/lib, so any package manager has to emulate that. My hope is that eventually, you can just run `cargo build --reproducible` or `meson build --reproducible` or `make --reproducible`, and if your architecture is the same, the dependencies will be the same and the output will run exactly the same. Even going as far as to install an older cargo or meson or CMake if that's what's needed for backwards compatibility. And if you want to be safe, you can create a sandbox or "jail" and libraries will know how to deal with it instead of just crashing when they try to access something outside.
