Dependencies of the Bazel project itself should be added into the Bazel Central Registry:

• bazel_skylib
• bazel_skydoc
• com_google_protobuf
• platforms
• rules_cc
• rules_java
• rules_proto
• rules_pkg
• rules_python
• rules_nodejs
• rules_sass
• grpc
• upb
• c-ares
• zlib
• abseil-cpp
• re2
• boringssl

Blockers:

• There should be periodic named releases. rules_cc#91
• Have a new release for stardoc stardoc#109

Notes:

• Currently we are writing MODULE.bazel files for those project and checking them in the BCR, that is fine because Bzlmod don't read MODULE.bazel from the source archive. But ideally they should be upstreamed.
