ssh support is present because Windows' pty story, while better than 5 years ago, isn't great. The integrated ssh support allows bypassing that layer when running wezterm on Windows and connecting to a real unix system.
serial port support is present because I do a lot of embedded work on multiple systems and want a consistent environment.
Multiplexing is there because that is actually what you're building when you add multiple tabs, windows and panes.
You can, of course, not use any of those features and still potentially enjoy using the ones that you do need/want. Or just not use it; I don't mind!
