| 17 | * This is NOT a substitute to real Profiling, but it proved to be |
| 18 | * useful to gather data in a way that the developer would like to profile. |
| 19 | * |
| 20 | * No production code should call methods from this trait. |
| 21 | * Feel free to commit code that uses this while the PR is under progress, |
| 22 | * but it should be removed before the PR is approved. |
| 23 | * |
| 24 | * @todo Add a PHPCS rule that looks for these methods and fail CI. |
