Reason that Google isn't seeing more is a) some BigCo v4 holdouts b) happy eyeballs sometimes landing on v4 because their v6 is shitty 6rd or something (e.g Free SAS)
The only ISP not putting out v6 widely is SFR, and thankfully they've gone bankrupt and we will be rid of this scourge.
The connection is solid, though - thus my lack of enthusiasm.
