  If GIN truly "breaks" SIP, then wouldn't that mean that SIP PBXs, and their UA's, would also need to be mandated to support GRUU (which doesn't seem to be the suggestion).

  Now perhaps something like an out-of-dialog REFER for Call Transfer to the SIP PBX won't be possible without GRUU. But is that truly a mandatory capability that is required to be supported as part of a basic SIP PBX offering by a service provider? Or would be ubiquitously supported/allowed by SIP PBXs?

GIN breaks significant parts of SIP without GRUUs (or some equivalent functionality) so I think we need GRUUs to be required to be implement on the SSP side of GIN.
