This is like saying "no we don't need a calculator for iPad, the first thing I do is go to the app store and find my favorite 3rd party calculator. Apple doesn't need to make one. this is fine"

It's not that this is causing people to lose sleep. The issue is that it's an easy, tangible fix which would benefit a lot of power users. Also magnet costs money and window snapping in Win10/11 is free.
