Right now, we compute the operator norm for the (possibly non-square) block and test with respect to a threshold.

However, we could use norm inequalities, and check if the 1-norm or inf-norm (induced norms) values are sufficient to draw a conclusion before computing the 2-norm.

Also, we could combine the connected components computations and the norm tests to avoid computing redundant values.
