If the deprecation is kept and furthered to a removal, then I don't know if it makes much sense to still have that function anymore (or more likely, simplify its implementation since it can't do superglobal filtering - since there are quite a few users of it after all, ~258k per a quick GH code search). Regardless, there's still merit in cleaning up flags and using enums regardless what path is taken.
