The operations in this filter are expected to be required for proper functioning of Solr, and it should not contain anything that could reasonably be removed, or replaced with an alternate configuration.
For the moment this is replacing MDC filter since we seem to have actually made a few portions of the solr code dependent on it. Depending on how SOLR-18050 is resolved we might re-extract MDC from the rest of this.
