TabView Sidebar Style Default?

I'm loving the TabView behaviour, but specifically on a landscape iPad, I'd like to have the app default to sidebar mode. There's tons of space, and for my app it just looks better. I'd like the TabView behaviour everywhere else, though.

I know I can set

  TabView {
    ...
  }.tabViewStyle(.sidebarAdaptable)

But what I really want is a .sidebarPreferred attribute that uses a sidebar where it would make sense, and a tab bar anywhere else.

Even on a portrait iPad I'd like to have the option to have the sidebar style be the default.

Is there a way to do this now, or should I open a Feedback?

Thanks
