Sanne Grinovero, Hardy Ferentschik: Some questions for you guys:

• Is the property "hibernate.search.default.write_metadata_async" established in HSEARCH-1728 actually still needed, if it can be set automatically depending on whether the backend is async or not? In other words, is there a need to set it to false for an async backend / set it to true for a sync backend? Otherwise it'd be nice to get rid of one of these knobs people need to reason about.
• If the property still is needed, why is it not named "hibernate.search. {default|<index_name}

  .infinispan.write_metadata_async"? The property only makes sense for ISPN, and IMO that should be reflected in the name. That was suggested already back then, but apparently that proposal was never picked up.
