Thanks for the thoughts, Karl. EACW's main sin, as it were, is a lack of documentation. My point in referencing the 1966 instruction is that it came from the Vatican, not some perceived radical cabal of liturgists.
Scholars are certainly aware that much of the impetus for the liturgical movement came from Europe.
Americans were relative latecomers. Current Vatican statements seem more concerned with politics than theology or openness to the Holy Spirit. At times, a nave needs to be described functionally. Karl, I can't paint a picture on the net of what I would imagine ideal worship spaces to be. I can assure you I am not an iconoclast.
