As a potential GSoC student and newcomer to the project, Faiz would
not have known that this would be considered unwanted churn when he
chose the task from the GSoC microproject page [1]. Perhaps it would
be a good idea to retire this item from the list?

On the other hand, it did expose Faiz to the iterative code review
process on this project and gave him a taste of what would be expected
of him as a GSoC student, so the microproject achieved that important
goal, and thus wasn't an utter failure.
