Third-party plugin is not recommended if a built-in plugin exists

I am developing a visual XSD editor plugin. The best way to reach my potential customers would be if the plugin was recommended to them so they could try it out. But as it turns out it is not recommended because the XSD file type is already registered by the built-in core plugin.

So I was looking for other ways to get my plugin recommended. Maybe another file type... But it seams all popular XML file types are registered by the build-in core plugin. So no third-party plugin that adds value to work with these files can get the benefit of recommendation.

Is this really how it should be?
