Well, in a word- Yes.
I think this is an incomplete understanding of tradition (in any sense, not just in regards to Church practices.)
The word “tradition,” as I’m sure you know, comes from trado, tradere - to hand over, transmit (or even teach.)
Therefore, a tradition isn’t a tradition unless it “stays alive,” so to speak, by being practiced and handed on by people alive today.
But, because times change, nothing can be handed on without also being changed in the process. Not everything we try to transmit to those coming after us can be transmitted in the same way; hence, many human customs degenerate or mutate over time because it is impossible to preserve the mind-set and circumstances of the past.
On the other hand, when we try to transmit more valuable things, (not mere outward customs or appearances) we must try very hard to preserve their substance; however in order to do this, we sometimes have to change the way in which communicate that substance so that it is effectively preserved. Hence when the Church passes on teachings, the language which She uses changes over time (rightly and necessarily so) while the substance of the teachings does not.
Not everything that has happened in the last forty years is a “novelty” (except in the strictly chronological sense.)
Those of us who wish to stay in the heart of the Church must (learn to) distinguish between substance and appearance. We should preserve all that fosters a truly Catholic culture and way of life, while discarding anything that is mere superficial or that is no longer of use in helping us to transmit the truths of the Faith.
