It seems to me that there might be substantial agreement here.  As I
understand John, he was positing two reasons for sending a DNT flag to
first parties: (1) when DNT is enabled, first parties shouldn't
circumvent the limits on third-party collection by collecting data and
then sharing it with third parties, and (2) some first parties might
choose voluntarily to go beyond what the standard requires when they
see a DNT flag.
