I think it's a blessing. For me the most wonderful thing about game development is learning. I could learn so many things already and thanks to large engines like UE, I can learn even more every day. The larger engines are often used at huge companies, where they can make use of pretty much every single feature sooner or later.

I love writing everything from scratch just for the sake of learning. And yet I love engines like UE for trying new stuff and real world projects.

In large code bases, automatic testing significantly facilitates adding new features. I don't really know how they test UE, though.
