All the official Bazel .deb files since Bazel 1.0 have been around 42MB See https://github.com/bazelbuild/bazel/releases/tag/3.7.0 for the latest release

Most open-sourced Google projects use Bazel now. Of course, projects like Android and Chrome have been around for a long time and have invested in their build systems, so any change will take years.
