I have a question, if the Faces built-in IOC is removed and use CDI as default, will it work with Spring in future?

That built-in facility has been removed a long time ago (in Jakarta EE 10), and we fully deprecated everything even longer (in Java EE 8 / JSF 2.3). It works with Spring, as there CDI simply replaced the built-in facility, while the business logic there remains to be Spring beans. So instead of having JSF using JSF Managed Beans in a Spring app calling out to Spring beans for business, you now have Faces using CDI "Managed Beans"  in a Spring app calling out to Spring beans for business.

From the point of view of a Spring app, both JSF Managed Beans and CDI "Managed Beans" are alien.

In the latter case there's a bit of extra integration work to do to keep the two apart, but it's doable as both technologies can veto and/or exclude scanning. I always hoped we could create an integration library (and/or add something to JoinFaces) for this.

Kind regards,

Thanks for the clarification.
Therefore, the old managed Beans were replaced by CDI, but we can use the _expression_ "Managed Beans" to talk about CDI when used at the Jakarta Faces level

Old managed beans (aka native jsf managed beans) were fully removed see https://jakarta.ee/specifications/faces/4.0/jakarta-faces-4.0#backward-compatibility-with-previous-versions

We did leave some traces of the term here and there, which are spec bugs. It's really good you mentioned this, so I'll take a look to remove them fully. The term "managed bean" was a bit overloaded. There were the JSF native ones, but also a pseudo super spec that made a lot of things in Jakarta EE managed beans (an attempt to unite all different component models), but this one failed / was overshadowed by CDI.

I think we mostly just call the CDI beans in Jakarta Faces "beans" or when they sit behind a page specifically a "backing bean".
