Markus,

> 
> * Is @Inject really needed for @*Param, or can we tell CDI that @*Param shall *imply* @Inject? 

 I think so, as long as @*Param are qualifiers. It may possible for implementations to provide shortcuts without @Inject, but I’m not sure we should encourage that.

> 
> * Why do we need @Entity?

 Because we should allow injection of arbitrary CDI beans as params, and if you have more than one, it’s not clear which one is the entity.

>

 Yes, just like today without CDI.

>

This means, we should be able to run on JRE 17 as this is the next LTS version, and we should clarify with the Jakarta EE team what the minimum JRE for Jakarta EE 10 is. We also should discuss whether records and sealed classes needs special support in Jakarta REST 4.0 as I assume both become rather popular in the next months.

 This is more of a community decision IMO. I’m not sure how to do some of the things you mention here while requiring support for a minimum JRE. Perhaps you can explain this a bit more.

 Where? In our API classes?
