Pretty much.What you would imagine this "you":
So, what changes could whoever is designing a version of D&D (assuming either WotC or someone who has approval to use the D&D brand) make and have the receiving public/target audience still consider it D&D.
For example, your first point was "races". If the next iteration of D&D didn't include races, you (as part of the target audience) could no longer consider it D&D, right?
That’s not based on market research or anything, but I believe it.
