Lucas has been contributing to Wikimedia projects for a very long time, has keen eyes for bugs and always fascinates me by his vast knowledge. My experience of working with him on daily basis in the last year was amazing and it's a surprise to me he doesn't have these rights already (he is a deployer!)
