Why is this a problem? It’s switching to the better camera for that shot right…
As a photographer, I would say a that's a resounding no. It depends on the shot. I'd rather control it myself. For instance, if I was taking a macro photo of a frog (or other small critter, bug, bee on a flower, butterfly, etc), which I have done quite well using 2X and more recently 2.5X optical zoom on my iPhone 12 Pro Max, and it switched to the ultra wide, I'd have to get very close to the frog. And while I might be able to capture an even closer photo, I don't need to, and the frog would jump away because the camera would be less than an inch from it, vs. half a foot away, which you can do if you move slowly and carefully.
This macro mode a nice new tool to have, and will be great for more extreme macro but I don't want it taking over for all my macro shots. I will definitely use it though. As a photographer I want to make the choice. And before people say that I'm not a real photographer if I use an iPhone, the best camera is the one you have on you, and besides, my camera gear is probably better than yours anyway, haha.
Personally my favorite macro lens isn't even traditionally considered a macro lens, but it works well for the smaller work that I do. I use the Sony 100-400mm f/4.5-5.6 GM, sometimes with the 0.4x adapter, because it has a relatively closer minimum focal distance which allows me to capture small wildlife from much further away than something like the Sony 90mm f/2.8 Macro G, which is a great lens otherwise. It's also good for flowers. I also believe it gives me a little bit more depth of field without losing beautiful background bokeh, but I haven't done extensive tests to confirm. I just like how it feels, and as a bonus, it's also a great lens for larger wildlife, birding, and sports.
So hopefully you can see how individual styles, subjects and environmental factors can affect which lens selections are made. Everything from depth of field, background blur (bokeh), available light coming into the lens for a given situation (which can result in more or less noise since the ISO has to boost), size of the subject, whether the subject is alive or otherwise prone to being disturbed, and more can affect lens selection and a photographer should always have control over that, especially in a phone labeled "Pro". And even though it is a phone, when it's all I have on me, I do take these things into consideration and try to make the best of my gear and maximize the limitations.
