Just out of curiosity, I started browsing the games having "Conquest" themes and "Conquest" mechanisms on BGA, and Kingdom Builder happens to be tagged for both:

From my personal experience with KB, it can certainly get very aggressive in terms of blocking each other's settlements and racing for location tiles, but I'm not sure if that's enough for KB to qualify for either Conquest tag.
I can't find the qualifications or constraints for theme tags and mechanism tags on BGA games anywhere either, so I'm wondering how these tags got applied in the first place.
