I can't say that I fully understand this issue, but Usenix has a package for displaying badges in the PDF for a paper with an artifact and maybe a standalone appendix for an artifact. If CiC starts collecting artifacts then we might want to extend iacrcc.cls with this capability. I suspect it would be better to create an independent package iacrbadges.sty and put it in CTAN so that it could be used in LNCS, ToSC, and TCHES papers as well.
