I think your confusing 'need' with 'want'.
Also the custom ROM's I've used and kept work extremely well and are properly stable.
PAC Man for example combines 3 ROMS (as you probably know) in one and includes all the wealth of extra's in a nice neat interface. Far more convenient and neater than multiple apps.
Battery percentage (in the proper place) or PIE control, or DPI per app all require root the last time I checked.
