It's long been a pattern of whatever Apple has for sale now tends to have abundant cheerleading for exactly that. So notch is in play now, sling the notch rationale much more so than anti-notch. In Apple things (like iPads) that do not have a notch, those things obviously don't need the notch... so notch-less makes perfect sense there. In other words, the same people can passionately argue FOR and AGAINST notches... seemingly driven by where Apple chooses to include a notch.
However, if Apple goes pill as rumored with next iPhone, the "I love the notch" crowd won't bash Apple. Instead, they will immediately roll with the pill and then defend it vs. anyone who expresses discontent with it...
...until Apple goes with something else... and then whatever that is will become the one and only right option and all other options will be "ugly."
In other words, even very passionate opinions about such things don't seem to be legitimate opinions held by the individual but fluid ones... that shift as Apple shifts. Think of the extraordinarily passionate arguments against phones with screens bigger than 3.5" and then 4"... until Apple went "phablet." Then- seemingly overnight- nearly all such anti-phablet opinion evaporated. Apparently (one-handed use) hands grew? Apparently developer fragmentation was not so difficult to deal with? I'm still looking for all the pants with bigger pockets.
Apple themselves just spoke very clearly about the notch with the new Studio Monitor having the camera but not having the notch. If notch was Apple "iconic" TO APPLE, Studio would have had it too.
Arguments like "it's not a notch, it's more screen RE to the left & right" should easily rationalize the pill rumor because pill would add
even more screen RE "around" the center area. Select apps that could get some menu content "behind" the notch would not be a
complete problem because you could see at least a little of whatever menu is "back there" with the added screen RE the pill option brings.
I think Apple will do away with the notch as soon as it suits Apple. And when they do, nearly all who so passionately evangelized notches will quickly flip to evangelizing whatever Apple has chosen as replacement. It's as it has always been... and presumably will always be.
