Not if a part of a line is out of the window right? This makes splitting harder, therefore, reading harder
"But then I can't see as many windows!" That brings us back to the GP's I need to see what I'm looking at, not what I'm not looking at". When you want to look at those other windows, bring them to the foreground and let them obscure this one.
I don't think that's enough of a reason to say the design choice is a sin for everyone.
Also word wrappings will lose all the preceding tabs. It makes it 100x harder to read.
The issue is I will have less split space.
This depends on your editor. I know VS Code supports indentation/alignment of wrapped words. I believe Emacs and Vim support it as well.
