Perhaps we can increase my "50" years to "200" years. For the vast majority of history, having less men was considered eugenic and a good thing.

It wasn't driven by having less men. It was driven by the upper class wanting more sex.
It also turned out to be disastrous for society, and most of the Islamic world has outlawed or severly restricted the practice as it leads to huge social problems.
The fact is that war has never been a large driver of casualties in these societies, outside of WW1 and WW2 which are the two exceptions and really don't prove your point. Wars were never fought to protect women, and most men died of disease and accidents, not war.
My main point of contention was that it wasn't a widespread practice and wasn't motivated by a lack of men.
