In other words, extrinsic tradition exists only on suffrance, regardless of its value.
On the contrary, if it's valuable, it will stay. This idea that all of extrinsic tradition has been cast aside after Vatican II is just laughable. Bishops still wear rings, just not with $10,000 stones in them, just as few wear jeweled mitres or carry gold crosiers.
I'm glad that the Church has tried to simplify many externals and become less regal in its bearing.
