Although it's true that people who know they want to use Wikivoyage can get around this, people who're searching for something like "travel to Malta" are the ones really affected by having the Wikivoyage results elided.
I guess this is a very heavy market, and there are a lot of SEO optimized commercial pretty-looking "travel guide" sites (although WikiTravel apparently belongs to that category as well).
BRB gonna stare at the sky and check that the stars are still moving as expected :p
