I have two quick questions:
- Why does `ComponentMetricGroup` even override the method
`getAllVariables` from `AbstractMetricGroup` with essentially the exact same
code?
-Why is it only fixed in `ComponentMetricGroup`? Could it make sense to fix
it in `AbstractMetricGroup` and remove the overriding method in the subclass?---
