Consider the FancyTextField:

@Composable
fun FancyTextField(value: String, onValueChange: (String) -> Unit, modifier: Modifier = Modifier) {
    Column(modifier) {
        TextField(value, onValueChange)
        Text("fancy!")
    }
}

While looking innocent, this code breaks the passed modifiers. If I pass for example Modifier.fillMaxWidth(), then only the Column will have expanded width, and the TextField will stay the same size, meaning that fillMaxWidth will not make FancyTextField fill max width (in practice). Obviously passing a modifier to TextField (instead or in addition) won't work well.

I propose having a parameter to row/column that propagates the minimum size to children Consider the FancyTextField:

@Composable
fun FancyTextField(value: String, onValueChange: (String) -> Unit, modifier: Modifier = Modifier) {
    Column(modifier, propogateSize = true) {
        TextField(value, onValueChange)
        Text("fancy!")
    }
}

And then fillMaxHeight()/fillMaxWidth() will work properly.
