@smaarn do we need this intermedeate package version or can we drop this PR and go further with #5817?

@hgy59 I think we have no choice but to go with this PR to fix current version and have the other MR done separately to keep a DSM 6 version functional.

At least from what I understood with the PHP 8 requirement starting from version 1.2.0

Just saw your comment on the "other" MR. Will be flagging this MR as draft and rework the latter.
