Personally I went through all of that after Florida. Now I aim for my my pages to have relatively low repeats and density of keyword I'm targeting and keep this near the top of the page so as to have high prominence score. Then I use a rich closely associated language with synonyms and semantically related words later in the page. The whole site then needs to build on this semantic richness.
As we get a better understanding of what is going on I think that the opportunities, which are bound to be opened up, are becoming more apparent.
