::::Summary Style is an option, not something that articles have to conform to. the problem with "summarizing" the History section is that it is already pretty much a summary. And a summary that exists as a result of a huge amount of debate and negotiation. We have not tried to make it lengthy, rather the reverse, but there is a limit to the extent you can summarize complex events without removing vital issues and context. It migth be interesting to see an attempt to summarize a subsection of the History section of the article. It would be an extremely difficult job to keep it balanced, weighted, cover all the issues, and be sufficiently illuminating.
