Hi, we can't do this change in a minor/patch version because it'd break people's baselines. This can be done by changing the error message only when the bleedingEdge toggle is on. You can inject the parameter into the rule with |

Outdated
| | `switchConditionsMatchingType` | Types in `switch` condition and `case` value must match. PHP compares them loosely by default and that can lead to unexpected results. | | ||
| | `dynamicCallOnStaticMethod` | Check that statically declared methods are called statically. | | ||
| | `disallowedEmpty` | Disallow `empty()` - it's a very loose comparison (see [manual](https://php.net/empty)), it's recommended to use more strict one. | | ||
| | `disallowedLooseComparison` | Disallow loose comparison via `==` and `!=`. You can use `includeOperandTypesInErrorMessage` to ignore some cases, for example `DateTime` object comparison. | |
