The trick is that now one will depend on somebody who is not boost for these nice mappings. I brought such a dependency for gRPC once and now it doesn't work with bazel 1.0. I either have to find the author, understand all the bazel trickery, or switch to something else, because most of these bindings depend on many bazel features.

So, bringing such multiple third party bandaid is currently not such a great idea. It would be a bit better if boost itself provided it.

Wasnt this because the dependency for gRPC was moved into bazel itself?

How is this different than most other build systems? You always have to rely on others.
