True, but also consider that there is "Standard delivery" and "Standard delivery - registered". Other services may offer "registered" in addition to "standard", but most couriers etc have tracking and SOD as standard, with things like insurance being the optional extras. 

 

Registered was removed from postage options after C&S was introduced, because registered was also discontinued for Australia Post's parcel service. It was eventually brought back because so many sellers complained about having to use "Parcel post - with tracking and signature" to indicate they were sending a registered letter.
