Actually, this is poor practice. Once the IAX2 specification was 
published as an RFC, the valid values for IAX2 commands, IEs, and 
various other components were placed into IANA registries. From this 
point forward, any future additions to these spaces *should* have been 
made by drafting an appropriate document describing them and requesting 
that IANA add them to the appropriate registry (which would result in 
numbers being assigned).

This situation is no different than if Asterisk wanted to start sending 
a new SIP request method without getting it registered (although SIP 
request methods have a much higher burden to meet before they are 
registered by IANA).
