Dear Karan,
As a part of the contrib acceptance process, can we spread the load a bit by saying that anyone who wants to submit a package, must also find someone else ( other than their sponsor ) to write a set of acceptance tests[1] for their package.
A process like this could easily be handled through package reviews via bucktracker. Maybe there is need of adding a 'review request' category.
A review could then contain a 'quality check' of the spec file (perhaps with Fedora Package Guidelines/rpmlint in mind), followed by a review of provided paches and a rebuild with 'acceptance test'.
Best Regards Marcus
