Well, there was extensive discussion last time around where people

Again, this came out from the last round of discussion that people
wanted to select which transforms to use and that the function needs to
remember that choice, so it doesn't depend on whether a transform
happens to be installed or not. Also, it's in the SQL standard that way
(by analogy).
