Not sure about your circle, but I believe most other Anglicans think about the RCC Church and Faith a lot, but implicitly. They don’t consciously say “We are moving away from the Magisterium on this issue, better be careful not to go too far”. But they take for granted certain parameters. They assume a template:
This book is in the New Testament canon, that one is not;
This ancient scholar is an Early Church Father, that one is a heretic;
This ancient church practice is consistent with the common Christian Tradition, that other ancient one is not;
This ancient dogma (Trinity, or others) is consistent with the common Christian Tradition, that other ancient dogma is not.
Apparently they hypothesize some anonymous, organized, authoritative ancient source for all these discretionary decisions that make up the template, they don’t make any inquiries about whether there is any organization today that might show some direct, organizational continuity with that hierarchy.
Apparently that ancient template-making hierarchy disbanded, with no direct organizational successor.
But I would say most do in fact think about the RCC Magisterium a lot, but unconsciously. It is the (to them) anonymous template maker.
