I know people who work at Google.
Revision of GG they tell me is the thing "no one wants to handle". Why? Because GG handles very extensive LEGACY.
And that legacy has features that Google does not want.
**RANT ON**
Long ago Google took legacy on in one interface to support both LISTSERV (email lists) and USENET (nntp: the "news-group" protocol). Both were vital during earlier internet.
NNTP: still exists and used, though most end users would not know about it, it having gone from a free non-centralised news distribution system to a usually paid for add-on.
But NNTP's de-centralised model of info sharing was and is brilliant. That was how the net was first thought about. It was conceived as a NET, not a HIGHWAY to Google.
Google's changes in GG function are incoherent. They are REDUCING function. It makes NO sense. The whole original POINT of GG was to be LISTSERV + USENET that is EDITABLE & BETTER LOOKING. To add value to them through a web interface.
IMO, it looks like some poor inexperienced Google folk were lumbered to work on "improving" it--with disastrous outcomes so far.
**RANT OFF**
