Not neccessarily if you offer classes difference avenues and specializations and let races and background lean on them.The issue with giving race, background etc more equal billing is that you gamify them and create optimal combinations. You want the fighter player to feel free to be a half-elf fisherman with skill points in obscure things without feeling like he's missing out by not turning every dial towards combat.
A Elf wizard is better at Ranged spell attack roll spells
An Orc Wizard is better a Melee spell attack roll spells.
An Gnome wizard is better at Transmutation and Illusion spells.
A Human wizard is better at rerolling dice in spells
A Dragonborn wizard is better at casting spells of their dragon type.
The issue is D&D tended to simplify not-class features to the point that any discrepancy in power is major.
