Shouldn't need the full blown Word to make a simple text document with different fonts and basic page layout options. WordPad is very lightweight, not like removing it saves any notable storage space.
It's not about storage space, it's about maintaining two programs that do the same thing. With modern computers built for Windows 11 and not minimal spec, ram should be plentiful and cheap to add if needed. Any computer with tpm2 it shouldn't matter with unless the build was bad to begin with.
Support from the development side of things. Every feature Windows pack has a cost attached to it. Microsoft tends to prioritize features that are used by most users and prune the others to cut costs down.
I used to put my Taskbar on the left, set every window to be a separate selection in the Taskbar, add my Desktop folder to the taskbar, and then make the taskbar super wide so I could read all the open windows and select what I wanted.
