One could also (IMHO) ask whether there are cases when the ISP would 
only want to offer non-registered mode.

In some networks where the ISP is capable of offering dual-stack
access or other kind of tunneling methods (e.g., L2TP as described by
Gert), the only interest from the ISP side could be this "zero
infrastructure -- zero hassle" mode -- non-registered.

To me, both seem to be applicable but in different context:  
non-registered is an auto-discovered or a "tryout" thing, or meant for
short-term fix.  Registered seems like a more long-term solution for
an ISP which is serious about v6 but cannot/will not offer dual-stack
services for whatever reason yet.
