Growing jextract

[Christoph Läubrich]

Hi Maurizio,

that sounds interesting, jextract is really a very useful tool, so maybe 
its a good opportunity to ask will it be part of the standard jdk 
distribution one time so one don't need to download it separately?

I also wonder now that it will become final in 22, will there be some 
kind of --release flag so one can generate code that is compatible with 
Java 21 and 22 (e.g. only using API that has not changed?), maybe even 
if the API evolves in later versions? or will one always need to make 
sure our self in some ways?

best
Christoph
