See "caches"; Gecko allows the UI to do a forced load from cache,
ignoring such headers.

And hence won't happen for what some will argue is a niche feature in
the first place.
Your argument seems to come down to "it's already slightly broken in
rare cases, so it doesn't matter if we break it completely in what we
hope will become the common case", honestly. Maybe you even believe
