I grew up in a house that had 3 back doors, a front and a garage door. Turns out that multiple remodels really messes with layouts. Where to put your shoes was a big issue

I think it's an artifact of this whole "your home is an investment" thing we do. It's like if you're not planning upgrades that make it look better on zillow (upgrades that potentially invalidate initial design considerations) then you're being financially irresponsible.
