Why do Docker/Compose examples use opentelemetry-collector-contrib while other sections use opentelemetry-collector?

https://opentelemetry.io/docs/collector/installation/

In the docs, Docker/Docker Compose examples use the opentelemetry-collector-contrib image (with /etc/otelcol-contrib/config.yaml), while the OS package/binary examples and many Kubernetes examples use the core opentelemetry-collector image (with /etc/otelcol/config.yaml).
I’m not sure why only the Docker/Compose section defaults to contrib—is there a specific reason those examples shouldn’t use core as well?
