| 15 | * we needed them to be in the service container for tests, |
| 16 | * so we added them there under WikibaseQualityConstraints-specific names. |
| 17 | * Subsequently, the service migration in Wikibase moved its services into the service container, |
| 18 | * which made this class mostly obsolete. |
| 19 | * It survives only for a few services that are not quite available from Wikibase directly. |
