Yeah.
But forcing you to get an iPhone in addition to your iPad just to be able to use your Watch is nicer for those who matter the most to Apple, its shareholders.
I'd gladly use an Apple Watch Ultra only and ditch my iPhone entirely. The battery life on Ultra is enough to last a full day on LTE:
But obviously, untethering Watch from iPhone defeats the entire purpose of the iPhone-exclusive accessory, to have iPhone eat even more shares of the smartphone market.
Independent Watch or Watch on iPad is mot likely to ever happen. Well, not unless some government enacts a new regulation. 😏🇪🇺
One can dream.
