Such systems may not be fashionable amongst some, but they do have

They are simple reliable and no moving parts. That's all. They are
useless for showers, take up much needed space, use a lot of
pipework, can accumulate debris and the occasional dead rodent in the
cold water tank.

But the previous poster was takeing as given that there is stored hot water
with its associated cold water header. He was simply discussing the pros and
cons of feeding the *cold* taps either from the mains or from the header
tank. I don't see the relevance of your remarks to that discussion.
