> There are instances of binary operations where the input sizes (e.g., matrix-vector)
do not cover a potential dense-sparse change, which causes outputs to remain in wrong sparse/dense
representations. For execution types such as singlenode as used in JMLC scenarios this is
unnecessary.
> Furthermore, for special cases such as ctable rexpand, the output representation cannot
be determined upfront and hence, we should similar to binary operations, check for sparse/dense
conversions accordingly.
