I have created a new merge request, it is simpler to cherry pick the commits than dealing with the conflicts.

mentioned in merge request !970 (merged)

Just to be sure that we are not waiting on each other (no need to do it quickly): Matthieu, we are just waiting on your approval.

It only affects code protected by LOGGER ifdef so all fine by me.

merged
