Simplify ResourceDictionary

In one of the controls, I saw that this is how they wrote their dictionaries

<Application
    ...
    xmlns:ui="http://schemas.modernwpf.com/2019">
    <Application.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <ui:ThemeResources />
                <ui:XamlControlsResources />
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>
    </Application.Resources>
</Application>

This is very good and simple, It would be great if the HandyControl also supported it something like this:

<hc:Controls/>
<hc:Theme Skin="Light"/>
