Control over setting "Discover annotated classes automatically" as the default for JPA Facet

When you enable JPA on a project it defaults to requiring having the classes listed in persistence.xml.

That's really an annoying default since then when you generate classes it will complain about the classes not be available.

Do we have any way to control this default when user chooses Hibernate platform or as a global override somewhere ?
