Though the Nova PTL can make a final call on difficult decisions, he is not there to bypass the normal nova-core branch review process, and should be called as a last measure only. He shouldn't overrule the nova-core decision, but only have a casting vote in the case nova-core members can't reach an agreement. Otherwise let's just say Vish reviews branches and give other nova-core members some vacation.
