Linter: revive, Rule: `cognitive-complexity` - Measures of how hard code is to understand. Should we enable it?

[zak-pawel]

Description

This issue starts a discussion about enabling:

• linter: revive - Fast, configurable, extensible, flexible, and beautiful linter for Go. Drop-in replacement of golint. Revive provides a framework for development of custom rules, and lets you define a strict preset for enhancing your development & code review processes.
• rule: cognitive-complexity - Cognitive complexity is a measure of how hard code is to understand. While cyclomatic complexity is good to measure "testability" of the code, cognitive complexity aims to provide a more precise measure of the difficulty of understanding the code. Enforcing a maximum complexity per function helps to keep code readable and maintainable.

Configuration:

(int) the maximum function complexity

Example configuration:

      - name: cognitive-complexity
        exclude: ["TEST"]
        arguments: [20]

Expected output

Decision about enabling or not enabling this rule.

I agree, similar to #15818 and #15808
