One theological consideration is also whether or not the Church can be said to "lose" things for a couple thousand years that it originally had, and then artificially paste them back on later, and whether or not that fits the model of Church progression that we generally think of as Catholic. Generally we evolve and unpack, not lose and restore.
Also, that most of these practices disappeared after Apostolic times if they ever existed in these forms in the first place, and then were not mentioned by the early Christian Fathers is worth considering. What if there were reasons why these things were not part of the parsimony of Apostolic Tradition that our fore-bearers received? That it so completely disappears so quickly makes me wonder if these were things temporary granted only in the aftermath of Pentecost and the first era of the Church, or even things that in some cases the Church decided were exaggerated and started to discourage.
There is actually potentially more to this than the surface level issues. It says something about what the Church is in a fundamental way if we accept these things as anything more than a human-driven method of prayer or meditation.
