I agree. If someone wants to launch a new PHP framework in 2012, they should at least talk about some of the leading PHP frameworks (Symfony, CodeIgniter, CakePHP, etc) and say why those frameworks are not adequate.
Optionally, one could include a discussion of why one should use PHP, but I realize there is convenience and brevity to be gained from simply assuming you are talking to an audience that is already sold on PHP, rather than Java or Ruby or Python or Clojure.
Do all Java, Ruby, and Python frameworks include a discussion of why one should use those languages? Seems to me that when you're evaluating frameworks, the language decision is probably already made.
I know its not perfect, and has some little loved features. But for me a language is a tool. And tools are meant for specific jobs. Like I wouldn't use a phillips head screwdriver where a set of pliers is needed.
If php is to advance we should welcome all tools that evolve it.
