Yes it will be a long time if it ever happens. Deleting data is hard work that requires a lot of preparation and has to be done without the safety net of backups. In many cases it will require changes to proprietary software. Keeping data happens automatically. Not having data that you're supposed to have becomes obvious as soon as someone asks for it. Holding on to data for longer than necessary only becomes a problem if there's a data breach (that cannot be covered up).
