Frameworks are very popular nowadays. Symfony, Rails, Django, or Dancer are all references for professional web development, and a Debian web server is no stranger to them. The libraries and modules that empower these frameworks are also popular, and it's important for system administrators to know how to set it up.
You have the option to use prepackaged frameworks or downloading and installing it yourself. The prepackaged frameworks may offer ease of set up and administration at the cost of an older version. You will also have security updates coming from the APT system itself.
