It sounds like the article is saying we could detect many events without using a planetary scaled detector It mentions a single detector being a 15kg Be bar chilled to near absolute zero. Certainly very very difficult, but not in the realm of sci-fi.

It can't tell us how it behaves (is it quantum? it it classical?) without detecting many events in sequence to be able to run statistics on (and if you miss one, your stats are wrong). One bar has a very low probability of detection, we'd need many, hence the expectation of planet-scale machinery.
