Once neither AP nor DRP are running MetricTasks in Gen 2:
- Remove the lsst.verify.gen2tasks.register and registerMultiple decorators from all MetricTasks throughout Science Pipelines.
- Remove any inheritance from lsst.verify.gen2tasks.MetricTask from all MetricTasks throughout Science Pipelines.
- Remove any reference to MetricsControllerTask from the documentation of individual MetricTasks (such as NumberNewDiaObjectsMetricTask).
- Remove the lsst.verify.gen2tasks package.
- Remove lsst.verify.tasks.TimeMethodMetricConfig.metric, which is not needed for PipelineTasks.
- Review the lsst.verify documentation to ensure there is no remaining Gen 2 content.
This ticket does not cover removing Job or its infrastructure, since we are currently still using it in Gen 3, but there may be non-obvious components that are bypassed in Gen 3 and should be removed now.
