I can go first this time, if that's okay.
There are complexities that will be introduced if you have regional income cut-off requirements that will change over time and that have to be kept up to date. One suggestion might be for rural versus urban income requirements, depending on the location of the family. That's obviously going to be a difference. It's something to manage if you start to do that, so I think you would have have to weigh that in balance with whether you reduce it overall.
