Worth keeping android/interoperability/cpp.html and chromium/interoperability-with-cpp.html in sync?

Android-specific and Chromium-specific parts of the course both talk about using https://cxx.rs for C++/Rust interop. Is it worth it to somehow unify some of the content?

In particular, both introductory slides (at android/interoperability/cpp.html and chromium/interoperability-with-cpp.html) have a diagram of how `cxx` works, but Chromium also has additional speaker notes where it lists some benefits (over manually authoring the bindings).

PS. Some of the content will need to remain Android-specific and/or Chromium-specific:
* Error handling (Chromium disables C++ exceptions, so Android slides don't apply)
* Integration with [Chromium's `gn` templates](https://google.github.io/comprehensive-rust/chromium/interoperability-with-cpp/using-cxx-in-chromium.html) vs [`genrule`s on Android side](https://google.github.io/comprehensive-rust/android/interoperability/cpp/android-cpp-genrules.html)
