"If you're maintaining an open source product that is meant for mainstream distribution then please do not do this, fixing bugs is not about closing tickets, it is about improving a product."
MySql is an open source project, but Oracle is not an open source organization, it's the biggest of BigCorps, with performance reviews, raises, 360s and for all I know 720s. I'm sure that bugs closed is someone's performance metric, and as we know, that which gets measured gets done.
