Quick Researcher Survey on GitHub Repos similar to yii

Dear yii developers,

My name is Raula Gaikovina Kula, an Assistant Professor and software engineering researcher at NAIST, Japan. I am writing on behalf of our research team that is conducting a study that traces the origins of source code within GitHub. Formally,
The aim of this project is to evaluate our proposed new approach of contributions to FLOSS projects. Because of the reusability of FLOSS, pieces of source code from the same origins spread to multiple software repositories are maintained independently, which can cause the obsolescence of source code and the increasing risk of defects and vulnerabilities. For these issues, we intend to aggregate various changes for source code of the same origins, compose integrated changes and distribute to FLOSS projects that have the related source code. We call this approach meta maintenance. We hope to be able to have a better grasp of understanding the important points of such contributions so that we can build practical tools for meta maintenance.

You work with yii has lead us to interview you on these specific changes. We gratefully request your time to tell us what your thoughts are on the topic. It should only take 5 mins.
