Don't all browsers handle incognito/private browsing in this way? From my pov they cloud not really do it any other way as long as pulling out tabs into their own or other windows is allowed.
Nope, I think in Safari all tabs are completely independent from one another in incognito.
To be honest, it’s sometimes a bit of a pain (e.g. when you are using incognito to just have a different identity, like to be on a corporate/personal account.) I wish a browser offered the idea of opening windows/tabs with selectable incognito identities.

That's exactly what the Firefox Containers feature is.
It's not that easy to use, and extensions that improve the UX or automate container selection are kind of messy. But it does work. It's excellent for when you need to use multiple accounts on a service.
