No, not really. That should be a sign that you might be missing something in the communication ...
The point we seem to be talking past one another one is what is core to the Dungeons and Dragons brand identity?
If you start botching / conflicting with established continuities and franchise settings like Forgotten Realms, City of Greyhawk, Ebberon, Castle Ravenloft, and Dragonlance to the point where you need to do massive redaction instead of just overlaying an additive module I think something's wrong with your definition of "core."
You can try in vain to misuse the word "bloat" (To cause to swell up or inflate from its previous size) and try to adopt it against Humans, Elves, and Dwarves but it's a losing battle. Try using the established continuity of Krynn, Oerth, or the Realms without Humans, Elves, Dwarves, Halfings, Half-Elves or even Gnomes and Half-Orcs without causing massive continuity nightmares. Good luck with that.
Those races can't be easily written off as "bloat" because A.) they've been playable for over two decades in the core and b.) core brand identity and existing IP works the company still wants to generate revenues are inextricably linked to them.
Dragonborn? Goliaths? Planescape, Krynn, and Ebberon-originated races? Not so much.
