Hi @nils-a, do you have a view on when this change may be implemented? Is there anything I can do to help with getting it implemented? We're looking at using Cake v5 on a project and would like to use this module as part of that.

Thanks!

@antonysmith-mando the change was merged into develop, I'm preparing the release of v8.0.0 now.
