It's not the level of similarity but the significant level of difference in popularity that separates humans and half-elves from halflings and gnomes.How does the level of similarity between gnomes and halflings compare to the level of similarity between humans and half-elves, or do genasi and tieflings? (Especially in a post Tasha world?).
Folding gnomes and halflings together makes the "Core 4" races pretty much even and I'm happy. Sure, humans are the clear winners, but, it puts our new race on par with dwarves and elves for being played, and opens up space for a new race to appear in the PHB. Again, presuming they don't just keep adding more races to the PHB. But, that would resolve my issues with halflings as being largely a waste of space in the PHB.
