When shadow DOM is used to create controls/widget, the @host rules could be
seen as a way to provide default styling for the box, surrounding the said
widget. 

For example, imagine that <input type="text">'s typical outline is actually
styled using @host rules. 

Now, I want to add small icon inside of the input field to indicate something
about the text content (calendar icon, for instance, to click and bring up a
date picker). Always applying @host to the shadow host is the desired behavior
here, since when I include the older shadow in my calendar icon shadow DOM
subtree, I still want the text field's outline to be on the host, not at
inclusion point.

However, if instead I want to add, say a password-strength indicator to the
right of the field, I do want to put the outline styles somewhere on the
<shadow> (but where?)
