I re-read what I wrote in that discussion in September, and I can see
how it was confusing: first I suggested those checks as possible extra
settings in the restrictions on FIFOs and regular files, then agreed
with you that we need a separate sysctl in a separate patch - but we
never discussed whether that separate patch should be part of the same
patch series or not.
