I fully agree with the solution. Spacer components are a sound concept if you consider that a component should have no awareness of the larger context it is placed in. A next step to make components even more robust is for them to respond to available space in the parent container (container queries). A spacer component is easy to understand and makes consistent spacing easy. There's nothing dirty or impure about it. You just mark it aria-hidden so that both search engines and screen readers ignore them. Another tactic is to apply component margin spacing on individual instances of a component, as a utility class. It will work most of the time, but is more fragile. There is but one issue: the internal padding of a component (which is perfectly normal to have) is visually experienced as a margin when two subsequent components share the same background color. In this scenario you're still theoretically consistent with your margins but visually it is not perceived as such.
