You may be right but it’s worth noting that many mid century kitchens - including my own - were less focused on hospitality in the kitchen and more on efficiency. In some cases this was because homes had hired help.

My MCM kitchen is large enough to host but the cooking area is like this galley. I love to cook. Having lived in a home with with a huge open kitchen, I vastly prefer this galley style. It really does save time. When you’re doing a few things at once, a large kitchen with a lot of space between stations is a liability.
