How easy is it to extend / change the Zend Framework?

Question

I recently started building version 2 of my old custom MVC framework. He did a great job for me on a number of projects, but I definitely see opportunities for improvement. It lacks some basic features, such as ACLs, form validation, and caching. As much as I would like to build these parts myself, I know that this is not a reasonable solution. So, I started to learn Zend Framework 1.9. I really like how his component library is loosely coupled. However, looking at various textbooks, this seems very verbose. I saw some sample applications that I could duplicate using less code with my own infrastructure. Thus, I would like to “override” most of this to make it more RAD friendly. Therefore, before investing a lot of time in the framework, I hopedthat someone can highlight this issue for me. I am an encoder at heart, and I have no problem spending hours on hourly settings and setting something up if it has a solid foundation (which I hope ZF has).

I should note that I am very pleased to see that Doctrine can be integrated with ZF.

If ZF is not easily extensible, then what other structures (which also have ACLs, form validation, caching)? I looked at Symfony, but the whole configuration throughout the Concert really bothered me.

Thanks in advance for any input.

Edit
To answer the tharkun question, I mean that “easily extensible” is that I can collapse my own classes (which may or may not extend ZF classes) and pack them into a structure so that I can easily create a code base for their own projects.

The main thing is that you can easily code the interface. Are you unhappy with the implementation of Zend_Acl_Resource? Create your own resource class that implements Zend_Acl_Resource_Interface :)
