The problem would be that it isn't an existing system until AFTER it is accepted. This requirement has been in the standard a long time so whatever the basis, it is lost as ancient history. A reasonable assumption (since it is allowed for existing systems, thus must still work) is that the 1/2 NPT unnecessary restricts the flexibility of a system that already has a higher flow demand than typically provided by K 5.6.
