Reduce cognitive complexity lint span #4935

Currently the cognitive complexity lint spans the entire function body making it really difficult to read and refactor the code in editors. To fix this we reduce the lint span to the function name.

changelog: Reduce cognitive complexity lint span

Fixes #4241
