The decision to include DotF in the Yoda/ Palpatine fight was not made by Williams, but by George Lucas. And I don't think DotF was used "extensively"; in full form only during the final fight between Darth Maul and the two Jedi, and in AotC only during Anakin's search for his mother.
That can't be called "extensively".

I would have loved a cue with DotF and BotH combined, but, well, you don't always get what you want.
