DW does have a mechanical impact from race though. It's baked into each individual class, but it's still there. Grim World, a lovely supplement (if you ignore the grimdark bits) for DW, specifically has races, each of which gives a move or effect of some kind.Race/Ancestry/Kin having a mechanical effect is quite commonplace as a result of D&D's disproportionate influence, both in TTRPGs and video games. However, as I know you know, there are also a fair number of TTRPGs out there where it has little to no mechanical impact: Dungeon World, Fabula Ultima, etc. It really isn't the end of the world as some other people make it out to be.
The one for "drakarn" (their dragonborn) is...that you can set stuff on fire in some contexts. ("Flamegut: When you belch, two things catch fire. Choose one. The GM chooses the other.") Well, that and for the fluff of their implied setting, all drakarn know each other--and are sterile, but they don't know why. Hence, their race is dying out (not of age or illness, just injury or the like) unless they can find their broodmother.
