Well, when I made this post I should have sent email to Vassili first. Here's the much simpler way to accomplish the same thing:

    aPage
      when: version valueHolder
      valueSatisfies: [:v | v = #latest]
      enable: level

the first argument is a value model. Whenever it changes, the block passed as the second argument runs and the module passed as the third argument is enabled or disabled depending on whether the block returns true or false.

As usual with Vassili's designs, it's simple and makes sense.
