Abstract: The embedding of sober spaces in locales preserves products $ X \times Y$ where $ X$ is quasi-locally compact. A completely regular space $ X$ has this preservation property, for all $ Y$, if and only if $ X$ is a complemented sublocale of a compact space. Equivalently, every closed subset of $ X$ is locally compact somewhere.
