Sure, database driven WP features, don't work - As they should.
You just need to select your plugins from a smaller set, and use external services like disqus for database based service.
And i think with time that thinking could lead to a set of plugins with good security through isolation.
As for hosting complexity - for many sites, this could be hidden from the developer and the client.
And regarding code complexity - how often are custom wordpress plugins or themes(without a site builder) required ? and how much developer time does it take ?
