Couldn't agree more.
It's really interesting to see a new generation of vertical specific, large scale CMSs emerge (like from publishing with Chorus from Vox[0] or Arc from the Washington Post[1]).
My problem with 'Enterprise CMSs' was always that they tried to sell one hammer for every single type of nail, and actually, use cases for content management are so varied (and often specific to verticals) that you buy a big generalist CMS and end up having to customise and mess about with it so much you're always left in the situation you described.
