https://chromium.googlesource.com/chromium/src/+/76942473295e92c2f34a6ed40a47a806dec38072%5E%21/#F4 looks kind of related, so does https://cs.chromium.org/chromium/src/components/policy/tools/grd_helper.py?q=get_grd_outputs&sq=package:chromium&dr=CSs&l=8 (called from https://cs.chromium.org/chromium/src/components/policy/tools/make_policy_zip.py?type=cs&q=make_policy_&sq=package:chromium&l=56)
