Meh. At the very least, why do half-elves get the same weapon proficiencies as humans, and not some combination of human-weapons and elven-weapons?
And Dwarves get proficiency in Handaxes, Battleaxes, Light Hammers, & Warhammers. This is an even worse set of proficiencies than polearms, as battleaxes & warhammers only get you a single die-size increase compared to simple weapons and no extra weapon properties. Though I suppose Dwarves are losing fewer ASIs than humans, so it makes sense that their "replacement" racial abilities are lesser...
Dwarves always had proficiency in handaxes, battle axes, and war hammers (along with throwing hammer) in 5E. Nothing has changed in that regard, though we didn't get to see Shield Dwarves...
