I think this needs some notes on the migration guide too.

Also as Andrea says we need something added to the 4.10 upgrade guide doc, see inside the docs folder from camel root dir

@Paul-Blanchaert thanks for working on this - let us know when you have the last bit done. Ideally no later by end of this month to make it for the next 4.10 release

@davsclaus
I've updated some deprecated code in generated artifacts in an attempt to remove the build issues.
Can you initiate a new build? or can I trigger that?

[davsclaus]

okay lets merge this and manual regen. And if there is some other bits still needed you can get new code from main and send another PR
