Analysis components (analyzers, tokenizers, token maps, token filters) can be removed from the registry over time. Previously, an index built with one of these would become impossible to open, rebuild, or query, since lookups failed with a plain "not registered" error. Now such a name is reported as deprecated instead. Opening, rebuilding, and indexing continue to work for an existing mapping that references one, with affected fields indexed without analysis. Queries that need to analyze text with a deprecated component still fail, but with an error that identifies it as deprecated rather than unknown. New mappings should reject these components by checking Validate's error for registry.ErrDeprecatedComponent.
