I am from time to time involved in the development of the CakePHP framework, at least often enough to have strong opinions on specific weak parts of the framework. I think your project might have potential, but the lack of tests and composer support is a serious flaw.

Your priorities should be tests, and documentation, before anything else.

I think that your efforts might be better spent on improving CakePHP; the developers have no particular concern for backwards compatibility in the upcoming major version (3.0). I would be interested to discuss all of your ideas related to this, please contact me at tenebrousedge @ gmail
