Such a change would break Hibernate Search integration.

I'm not strictly against it as we can catch up on the Search side, but
it introduces a burden for end users to be aware of which precise
versions they will need: typically we promise that any "micro" in the
same major.minor will be compatible, so we'd be violating this rule.
Anyone not using this method would be unaffected so this seems a very
minor point but I think the "stick to the rules" part is more valuable
to keep people from worrying.

On which interfaces do you plan adding this method exactly?

You don't plan on actually updating the JPA API we use at build time right?

Thanks,
