Do we need a screenFacade.defaultRenderMode?

I’ve been studying the screen rendering code in my attempts to test the qvt2 code. I have some test code:

<widgets>
        <container id="app-root" >
            <screenLayout>
                <headerLayout>
                    HEADER
                </headerLayout>
                <pageLayout>

                </pageLayout>
                <footerLayout>
                    FOOTER
                </footerLayout>
            </screenLayout>
        </container>

    </widgets>

I have a custom ftl file to handle the processing which includes the DefaultScreenMacros.qvt2.ftl file. But in order to use that qvt2 ftl file, I need to call it with ‘?renderMode=qvt2’ in the url. This is because ScreenRenderImp has at line 396:

 if (renderMode == null || renderMode.length() == 0) renderMode = "html"

Wouldn’t it be better to have a ScreenRenderImpl.getDefaultRenderMode method so that the URL doesn’t have to be touched if the whole app is going to be run in say the qvt2 mode?
