Dwarves already have those proficiencies in EA, I don't think they're getting anything new here.
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...
Fair, but it'd still be nice if they were given something additional to replace the lost ASI for the Mountain/Shield Dwarf subrace. I suppose as it is unshown, it's still possible they'll get something....but given humans & half-elves it seems unlikely
