I created “bazel” to discuss the Bazel build system in the “peripheral” support tier (utils/bazel): llvm-www/LP0002-BazelBuildConfiguration.md at main · llvm/llvm-www · GitHub . I hope that this is a good use of a new label:)
Folks in the #bazel_build Phabricator group (Login) may want to help triage the issues.
