P2 Description
https://pkg.go.dev/github.com/apache/beam@v2.29.0+incompatible/sdks/go/pkg/beam renders an error "Documentation not displayed due to license restrictions." It's unclear what the exact complaint is (speculating it could be a transitive dependency?)
This doesn't affect 2.28 & 2.27 (did not check further back)
