I don't disagree with the notion that a developers experience using an application might be vastly different that of a regular user and that developers might forget the fact. Then again, even if a developer cares about performance, if it's not set as the main goal or given any resources to pursue, it will still not get the much deserved attention. Performance on lower grade consumer devices should absolutely be a minimum pass criterions, but if it isn't, giving developers older devices will not help.
