No. The class name you use in your stylesheet won't be changed, so it
will apply to the whole document (because "scoped stylesheets" do not
exist); that's why the documentation talks about "legacy CSS".

I think browsers wouldn't choke on @external, but other CssResource
features (@sprite, @def, @if, etc.) obviously won't work outside of
CssResource, i.e. in ".html resources".

Why not just use the class names instead of trying to make it fit into
a CssResource? (<g:MyWidget addStyleNames="my-MyWidget" />)
Otherwise, you could define a CssResource whose *.css source is only
made of an @external rule listing the class names from you My.css that
lives in your war directory, so you have a CssResource interface
based on a non-CssResource-aware stylesheet (you'd have to inject the
stylesheet into the page by other means than
CssResource::ensureInjected() though)
