Note you'll need to update docs as well, to mention the new component types in that list:

quarkus/docs/src/main/asciidoc/hibernate-orm.adoc

Lines 543 to 561 in 206858a

	==== Plugging in other custom components
	The Quarkus extension for Hibernate ORM will automatically
	inject components annotated with `@PersistenceUnitExtension` into Hibernate Search.
	The annotation can optionally target a specific persistence unit with `@PersistenceUnitExtension(name = "nameOfYourPU")`.
	This feature is available for the following component types:
	`org.hibernate.Interceptor`::
	See <<interceptors>>.
	`org.hibernate.resource.jdbc.spi.StatementInspector`::
	See <<statement_inspectors>>.
	`org.hibernate.type.format.FormatMapper`::
	See <<json_xml_serialization_deserialization>>.
	`io.quarkus.hibernate.orm.runtime.tenant.TenantResolver`::
	See <<multitenancy>>.
	`io.quarkus.hibernate.orm.runtime.tenant.TenantConnectionResolver`::
	See <<programmatically-resolving-tenants-connections>>.

Please remember to deprecate the metadata build contributor, now that you're introducing an alternative.

A @Deprecated annotation + @deprecated javadoc tag there would do the trick:

quarkus/extensions/hibernate-orm/deployment/src/main/java/io/quarkus/hibernate/orm/deployment/HibernateOrmConfigPersistenceUnit.java
