Relevant DCA experiment is the "Open" one. Note that there are a number of new extraction errors on SideStore due to module version mismatches, giving a reduction in the number of alerts. Since we already have a number of similar errors on other DCA projects I propose we accept these.
a04b10c is somewhat of a hack to work around some data set check errors visible the integration tests. I wonder if there is some more principled way to deal with unavailable declarations. I did not investigate this further are part of this point update.
