My past three employers code bases: mono-repos, Bazel, lots ot C++ and Python, thousands of libraries and tools, code generation and modeling tools that are fully integrated into the build, easy cross compilation, large integration tests just one bazel test invocation away, hermetic and uniform dependencies...

Bazel Python does not cross compile IIRC. How was this achieved?

[simfoo]

Python is only used for build-time tooling (modeling, code generators) and developer tooling. All the on-target code is C and C++, and only that is cross compiled (Linux, QNX, various RTOS and x86+aarch64)
