No that is a bit extreme.Like SUNRAY (although undoubtedly not on the same scale!), I have installed a good few in my time. They can be quite useful for many things, none of which have been clocks for decades!
Last one I did that for would have been about 1984-5Hence, if you were to ask people how many (if any) they had installed "to connect clocks" in the past 25 years, then I imagine the answer would be much closer to zero

I re-used an old one about a year ago for a ring doorbell where the 13A plug kept getting unplugged to charge phones/nintendos/Ipads and changing the SSO for a DSO didn't solve it.
