How can we build Pages that fit the longtail keywords, without this data?
The point is that Google no longer wants you to "build" a page for a longtail keyword. It wants you to build a site that answers the intent of a wide range of related potential keyphrases. No site can cover every potential keyphrase on a page by page basis with out serious duplication of information, which is detrimental to a visitor experience.
Google came to the realization a long time ago (I think) that the way their algo was, could not efficiently deal with every potential keyphrase. I think they had already turned their algo to dealing with this, but Hummingbird is just a way to do it more efficiently from a computing standpoint. Which is why it has not appeared to affect much.
