To enable this feature, we copy the required proto file from
ChromeOS. Not a great solution, but better than leaving the
code uncompiled in upstream.
We could consider downloading the file from gitilies with
a fixed sha that is manually upreved. But unfortunately
downloading things in build.rs is not trivial without adding
a ton of dependencies for the reqwest crate.
