Looks like we are always in the True branch, we could potentially delete the False branch

Turned out elements can be () when doing something with VertexOnlyMesh.

Any good reason to introduce this kwarg? Could we not always create a CellSequence when the elements are on different cells?

We make CellSequence for proper MixedElements, but not for VectorElement or TensorElement.

What if we had:
elem = MixedElement(...)
elem.cells # always gives a CellSequence
elem.cell # crashes if elem.cells are not all the same cell, otherwise returns the unique cell
