I was expecting more changes here to retrieve the "default layout" from the block support config and apply it when the "layout" attribute is empty.

Not sure what you mean here?

For now the default layout value in theme.json has not a type prop. It assumes it is the default/flow layout and this is how it is used for example in Group block. With the expansion of new layouts wouldn't we want themes to provide some defaults for other layouts as well?

In my mind, the theme provides a single default layout and chooses its type and doesn't provide defaults for all layouts. The default layout is automatically used in the post editor canvas.

So the provided by the theme default should be only about flow layout, no?

maybe a theme would want to use a "grid" layout by default or some other layout we didn't build yet but yeah in most cases, it will be a "flow" one I think.

const defaultThemeLayout = useSetting( 'layout' );
const themeSupportsLayout = useSelect( ( select ) => {
const { getSettings } = select( blockEditorStore );
return getSettings().supportsLayout;
}, [] );

// TODO: If we implement layout for blocks and replace
// current display of them like this PR explores, shouldn't this check change?
if ( ! themeSupportsLayout ) {
return null;
}

const allowLayoutSwitching = canBlockSwitchLayout( blockName );
const { inherit = false, type = 'default' } = layout;
const {
allowSwitching: canBlockSwitchLayout,
default: defaultBlockLayout,
} = getBlockSupport( blockName, layoutBlockSupportKey ) || {};

const usedLayout = layout ? layout : defaultBlockLayout || {};
const { inherit = false, type = 'default' } = usedLayout;
const layoutType = getLayoutType( type );

const onChangeType = ( newType ) =>
setAttributes( { layout: { type: newType } } );
setAttributes( { layout: { type: newType } } ); // TODO needs checking with block defaults.

I'm not sure yet 😄 . I'm adding some comments to check it more when the time comes. I just thought I should check if we would need to add the defaultBlockLayout props if exist as well, because this line will trigger a rerender and the logic is if layout is truthy. Therefore I'm not sure it will behave properly.
