-  # The cognitive complexity of many of functions handling lower level network
-  # interactions can be quite high, and even some relatively short functions can end up
-  # being marked as too complex, due to the logic they contain (such as bit manipulation)
-  # Splitting these functions up would often actually end up decreasing the internal code
-  # readability, and also a drop in performance due to function call overhead.

-  # For that reason, many of the checks are either disabled or have their threshold set
