"Almost never" implies that extreme conditions can and do exist. That is the reason for testing at extremes. To improve on existing technology and develop new. All product development is done by testing at extremes, as you are well aware.
Tell those that live and work in extreme climates that they don't exist.
You are allowed your opinion and it is respected.
PS. I actively participated in battery testing at extremes from Fort Greely Alaska to the Yuma Proving Grounds for 39 years.
