Yes, currently less than 0.05% of end users and usually because they =

really don't.
One could make a valid argument that this is no worse than systems with =
misconfigured IPv4 who cannot reach Google at all even if they don't =
publish AAAA records because their IPv4 is so badly misconfigured that =
it doesn't work either. I suspect it may well be approximately the same =
fraction of systems, though it may take longer to notice/resolve the =
IPv6 issues than the IPv4 ones.
