Back when I was Catholic and whenever I would ask people who should know (my priest, these missionaries I knew) if rejecting Vatican II makes me a heretic to their mainline church (i.e. not SSPX or Sede), I would get nondescript answers or basically "yes" via a roundabout answer.
Roman legalism is so confusing. There are tradcaths who claim to be in communion with their pope but acknowledge their pope is not Catholic. To be in communion doesn't just mean to respect the office. My heart goes out to them because those mental gymnastics must be difficult to maintain.
