I don't favor arbitrary requirement for studies but I think it's fair to acknowledge that whatever has grown organically over the years does have legitimate reasons why it's the way that it is, even if it wasn't master planned (arguably it probably makes more sense if it evolved) and so you cant really assume that the status quo can be dismissed just because it's not consciously deliberate
It presumably had a good reason for being in each intermediate state before the one you became attached to, and people were presumably attached to those.
