Actually, 5e did bring that stuff. Evil nazi racist Tasha book tried to ruin it with its hateful racism. Dwarves, elves, orcs, Dragonkin et AL are not human, but for some reason everyone want these races to be humans with different skins. It is ridiculously racist. When I choose dwarf I want to be a dwarf in a fantasy dwarf not just a short human (which is absolutely fine as a character choice). But a dwarf is not a human -something that racist Tasha writers and their fanboys dint get.
All dwarves are naturally healthier than a human. Period. Even if a dwarf grew up in a human town in a libaey surrounded by books, she'd still be healthier than you typical human in the same setting. She's a dwarf not a human. That's why dwarves get the bonus con. Capiche? CAPICHE.
