I am not sure.. But, can't they be added with <vb:if condition>? Like a extra plugin at {vb:raw template_hook.headinclude_css}

That'll probably require manual removal of the existing calls.

And, what about the ability of adding custom js files?
Like, I have a few modification installed that requires js files to be loaded. A filed to add them manually would be much appreciated.
