GS I don’t understand why you seem to assume that important things are only those that are trumpeted and cut into stone by authority?
When my mother passed away us children shared out the five rings dad had gifted her over their lifetime together. I was very happy to be left with her comparatively cheap and simple band - one of the oldest. My sisters went for the expensive “rocks” dad gave her in later years when he had more money.
Illogical, unimportant, peripheral? Not really. I always remembered her hands nursing me when was a child and this ring is imprinted in those memories of her.
Clearly in the Church, like my sisters, like life in general, there are things not everybody understands or appreciates for a variety of reasons even in the same family.
“The Church” only tends to make an “official” song and dance about such things when they are in danger of being maligned or misunderstood or de-valued.
It sounds like you may be in the latter camp? If so, trying to ignore them as optional beliefs looks like a dead-end re trying to come to terms with the illogical emotion we have towards them that seems out of balance with your logical analysis of their “importance.”
Such difficulties may indicate a need for growth in the area of the heart and a turning down of the volume re the head
