The first one is for accessing the solution in the LocalOperator, as you need to read
from that container. The operator for the matrix is not required in the LocalOperator,
but you still need to read all those contributions in the assembler when copying them
to the global matrix.

These two methods will not be available on the residual and jacobian containers in
the local operator (as you get weighting accumulate-only views of them that do not
forward those methods).
