Someone correct me if I'm wrong here, but afaics dropping the ability to do it would remove a complication from the platform and wouldn't affect the vast majority of users in any way. But [afaik] it has to exist because Ericsson require that feature. Outside of their specific usecases it's doesn't seem a particularly useful feature, or one that is used in the vast majority of contemporary codebases
