Please keep the discussion on the mailing list rather than commenting on the wiki (wiki discussions get unwieldy fast). Confluence supports inline comments that can also be used.

Motivation

Use a standardized dependency injection in Solr instead of our home grown @SolrCoreAware, @ResourceLoaderAware, @SchemaAware etc.

Public Interfaces

Many plugins will change API which will affect back-compat.
