Should schools do away with the family tree project?

Every year the kindergarten class does a family tree project. They have been doing this as long as I’ve been teaching there And I even remember doing one when I was a child. This is usually what the worksheet looks like.

Now as you can see there are spaces for grandparents, mother, father, and siblings.

The child draws a picture of that family member. It is pretty obvious when a family members space is blank. I have heard kids ask other kids why didn’t you draw mom or why didn’t you draw your dad. This is how life goes sometimes and you can’t shield children from everything. But should these family tree projects be done away in schools. This gives the image that all families look the same but the truth is some kids only have grandparents, some only one parent, while others have 2 dads or 2 moms. What’s your opinion on these kinds of projects? Is it stressful or uncomfortable for the children who’s family tree does not look like this or a learning experience that everyone’s family is different?
