Can you elaborate why sharing a ConfigSet object would cause users to see different behavior?

> The objective is to minimize the heap usage where nodes host very large number of cores.
> A very common usecase is where all (or a lot of cores ) in a node uses the same configset. . We will make this an opt-in feature so that a common user wouldn't see a different behaviour.
> To enable this feature, add the following flag to {{solrconfig.xml}}
> {{<shareCoreData>true</shareCoreData>}}
>  
> I shall open sub-tickets to enable sharing of specific objects
