I very much hope this doesn't happen!

Some people might be able to create nice-looking posts and pages like that, but most will just find it an easy way to create ever more hideous sites. Think of what would happen on a site with many contributors, each trying to design their own posts. Ugh!

As others have said, there is a big difference between creating content for a blog and creating it for a CMS. For my own CMSs, I'm never going to be writing the content direct in WP anyway, because it's never going to offer the sort of tools that are available in dedicated writing software.
