I have doubts that the binding is still maintainable/reviewable. First,
why do you need all above patterns after removal of entire contents?

Second, amount of if-then-if-then located in existing blocks (not
top-level) is quite big. I counted if-then-using defs, where defs has
patternProps-patternProps-if-then-if-then-properties.... OMG. :)
