From the docs:"If resource_class is not specified or an invalid class is specified, the default resource_class: medium will be used"https://circleci.com/docs/2.0/configuration-reference/#resource_classMost jobs we run don't need 2vCPU + 4GB, so to optimise the resource usage across the company (many teams and pipelines) and improve developer experience (more parallel builds) we would like to be able to tune this value to our needs.
