automatically generate op convenience overloads?

Should we extend the code generation for ops to automatically generate convenience overloads? This would help reduce the gap between Python notation and Java notation.

As an example of where we stand now, here's some Python code (keras/metrics.py, around line 2203):

    dp = p[:self.num_thresholds - 1] - p[1:]

And here's the corresponding Java code (AUC.java, around line 809):

    Operand<T> dP =
        tf.math.sub(
            tf.slice(
                p, tf.constant(new int[] {0}), tf.constant(new int[] {getNumThresholds() - 1})),
            tf.slice(p, tf.constant(new int[] {1}), tf.constant(new int[] {-1})));

Start by comparing the Python example in keras/metrics.py around line 2203 with the Java implementation in AUC.java around line 809. Determine which convenience overloads should be generated and how the Python and Java forms should correspond; done requires an agreed generation scope and resulting Java API.
