They went with the same logic they have in control center, for instance if you just press the timer button, it takes you to the app but long pressing gives you an integrated quick timer selection.

I thought the same as you when it was presented and I understand what you mean. But now that I have it, I find myself wanting to go to the actual app more often than just wanting to peek into the shorthand version. For instance, when using the new Apollo live activity, when I interact with the island, I want to go to the thread in-app not just peek into it.
