This pull request is fully signed and it will be integrated in one of the next CMSSW_10_6_X IBs (tests are also fine) and once validation in the development release cycle CMSSW_12_0_X is complete. This pull request will now be reviewed by the release team before it's merged. @silviodonato, @dpiparo, @qliphy, @perrotta (and backports should be raised in the release meeting by the corresponding L2)

Hi @qliphy is there a plan for a patch in 10_6_X in which this can go to?

[qliphy]

@tvami How urgent is that?

@cms-sw/xpog-l2 @rappoccio

[tvami]

@tvami How urgent is that?

It's not super urgent, we'd just like to understand what the plans are, if there is some time when it would be best to plug this in.

[rappoccio]

We should probably discuss at the ORP meeting Tuesday. Are there plans for imminent papers that require this? If so we would need some kind of discussion / request / approval w/ Physics Coordination @arizzi.

[tvami]

Hi @qliphy @perrotta I wanted to wait for (the backport of) #34640 to get merged, but since it's going very slowly, maybe it's time for having a new 10_6_X release now that we are after a month of this PR? Is there anything else that's forseen to enter 10_6_X soon?

[qliphy]

@tvami Yes, we will make a 10_6_X this week, which will also include several features from GEN (will report at PPD general this Thursday) and PdmV.
