You should be careful making such statements to an audience in which many have been around when IDEs were invented.
It's certainly a useful thing to have, and yes, these days many IDEs do have it. But Xcode itself is from the time long before that feature became the default. And, unfortunately, it is mostly still stuck there.
when your IDE crashes (inevitably), you lose the entire console context and all running processes within it. There is also no way to detach the terminal from the IDE, say when the IDE needs to be updated (constantly).
IDE terminals also tend to be buggy.
I invite you to back up your claim by researching the following (as a starting point).

(Thanks Claude, once again you have been more helpful than a human, which is more than a little concerning.)
I don’t know if all of these are real or qualify as IDE’s, but I hope I’ve made my point: it turns out using the word “every” is a broad and bold claim.
And please don’t simply backpedal and say that you meant “most” unless you’ve actually done the research.
