The OP describes the specific problem this causes. It’s expected that these types of boxes are attached to studs and have void space next to them on the other side. Deviation from that pattern can cause issues with later installations expecting studs in some places and voids in others.
I can understand that, it’s why we have standardization. But the fault also lays on assuming everything is exactly as expected. Otherwise we wouldn’t need stud finders at all, we’d be sure where every last 2x4 is. A depth measuring stud finder would tell you there’s an unusual mass and give you warning that all isn’t like you’d expect.
