everytime we want to use it, call ensureInjected() ?
Styles need to be injected into DOM only once. Typically, MyResources would
be a singleton. There would be a static constructor somewhere:
static {
resources = GWT.create(MyResources.class);
resources.style.ensureInjected()
}
Calling ensureInjected in the entry point works too.

The styles can be included in .html file, but having them in a bundle allows
packing the styles together with your components (similar to using
<ui:style/> in *.ui.xml)

Yes, according to the guidelines

When we use <ui:style/> in *.ui.xml, CssResource and ClientBundle are
generated for us anyway, and there is a way to access them from code (the
link above). So we are already stuck to the ClientBundle anyway :-)
