ArchiveTeam uploading of Google+ content to the Internet Archive
So it turns out that fetching data from Google was only part of the archiving process -- the other is sending that to the Internet Archive. That's what this image (and link to the tracker) shows. About 2/3 complete by my eyeballing here:
(That's going to be relatively current for the next day or so, given it's a relative date offset of about 15 days.)
I've also heard that the Communities fetch may not have been as successful as hoped. Again, that was intended to capture effectively the paginated views of G+ communities, though it was an additional goal, and started late in the process. The contents should (mostly) make their way to the Archive, but it may not be easy to navigate by Community there.
