Yes ... and no.
It can depend on the functionality of the home.
You can appreciate how our lives have changed. In another era, when it was assumed the "woman of the house" would spend most of her hours in the kitchen, it made perfect sense. In years past, when most people farmed, it was essential to have a room close to an entrance where someone could wash off the labors of their day. If the room is next to a door to the outside, it was probably considered an upgrade to a mud room.
These days, the kitchen - not the television/media room, nor dining room - is the gathering area for the family. So, floor plans have changed.
I think it can work well as a room off a laundry/mud room, particularly if the dining room is two rooms away. There may be no getting around this sensitive issue in an older, smaller home with two bathrooms. Family members figure out how to get beyond it.
For many restaurants, the restrooms are just off the kitchen. There is usually a partition or a hallway off the dining room to access the facilities. Smaller restaurants put the bathrooms at the back, sometimes behind the kitchen.
If the entire floor of a home is dining room and kitchen, the answer may be converting that room to a half bath or removing it entirely. There are certainly ways to avoid the issue for the thoroughly charming smaller home.
