Rule S1172: Unused method parameters should be removed tries to detect the usage of method parameters. If we look the following example:

public class Compliant
{
    private static long InlineUsage(int value) // FP, value is used by the inline function.
    {
        return Inline();

        int Inline()
        {
            return Random.Shared.Next() > 42 ? value : 42;
        }
    }
}

It fails to detect the (conditional) usage of value in the Inline() method. Removing the conditional part (or making InlineUsage(int) public) resolves the issue.
