@Barthelemy @vascobarroso This will require a new version of FairMQ (already merged in alidist). Is it ok to merge or do you plan to do a release soon with new O2 and old FairMQ?

I think it is ok to merge, we don't plan any new releases in the next 2 weeks until the Oxygen run is finished.
But there is an issue with StfBuilder and the new FairMQ, Lubos is looking into it but until we have a fix we are stuck.

The issue with DataDistribution has been understood and fixed. See 14537.

Since everything seems to be working and the DataDistribution got tested by @lkrcal on staging, I am merging this given it's basically just cosmetics (i.e. FairMQ in alidist is already using std::pmr).
