Yes, eventually the post title should work exactly like other blocks. It may seem a little weird right now given what we're accustomed to. But, thinking long term, the entire post title/header area should be a block or group of blocks. This would allow users to easily do something like a full-width image behind the title with perhaps the post meta, intro, etc. (whatever they want).

I currently have a system of doing this with a mix of a page template that removes the title plus me manually adding a cover block in the post content. It's terribly complicated for the average end-user.
