FWIW Python has been successfully deprecating and removing identifiers for about a decade. They warn for maybe one or two release cycles (ie, in an x.y.z scheme, from x.y.z to x.y+2.0), then the obsolete name gets a one-way ticket to a senior community in Arizona. However, they also support a full release cycle older than the current release, plus security updates (source-only) for two release cycles before that.
