On a recent patch upgrade (9.22.1 to 9.22.4) the support for "pack" extensions has been suddenly removed.
I realise they were not officially supported, but it fit snugly on our use-case so we used it to group some stuff and delivery some features.
Is there any plan to reintroduce them in some form? do we have to migrate to bundle extensions (which are equally undocumented)?
shouldn't a structural change like that require more discussion or at least a minor version bump?
