SwiftUI layout inside VStack using ViewModifiers

I have a simple view with two texts. Its body is like this:

VStack {
    Text("One")
    Text("Two")
    Text("Three")
}

this produces a view like:

Existing layout

But what I would like is, using only modifiers to the Text views (i.e. no HStack with Spacers), achieve a layout like:

Desired layout

Is this currently possible? I was hoping making the Texts full width somehow and then just using the text alignment would work but haven't figured it out yet.

Well... as there are no any additional conditions or restrictions, with just added two lines of code

Demo in Preview (blue border is just a selection in code)

demo

    VStack {
        Text("One")
            .frame(maxWidth: .infinity, alignment: .leading)
        Text("Two")
        Text("Three")
            .frame(maxWidth: .infinity, alignment: .trailing)
    }

One approach is to just set the frame:

struct ContentView: View {
    var body: some View {
        VStack {
            Text("One")
                .frame(minWidth: 0,
                       maxWidth: .infinity,
                       alignment: .leading)
            Text("Two")
                .frame(minWidth: 0,
                       maxWidth: .infinity,
                       alignment: .center)
            Text("Three")
                .frame(minWidth: 0,
                       maxWidth: .infinity,
                       alignment: .trailing)

        }
    }
}

Yes, this could be possible. You could define a modifier like:

extension View {
    func horizontalAlignment(_ alignment: HorizontalAlignment) -> some View {
        Group {
            if alignment == .leading {
                HStack {
                    self
                    Spacer()
                }
            } else if alignment == .trailing {
                HStack {
                    Spacer()
                    self
                }
            } else {
                self
            }
        }
    }
}

And use it like:

VStack {
    Text("One")
        .horizontalAlignment(.leading)
    Text("Two")
        .horizontalAlignment(.center)
    Text("Three")
        .horizontalAlignment(.trailing)
}

Of course, multiple approaches are possible.
