What happened to the Racial Substitution Levels?

[Byronic]

Anyone else recall the 4e talk about how Races would gain powers at later levels, and how they would have Racial Substitution powers for certain classes, so that a Dwarf Fighter would gain different powers than an Elven Fighter, for instance? What ever happened to that? I don't see anything like that in the books, though there are a few Racial Feats you can take for certain races.

I was hoping for that as well. If they must equalise EVERYONE then at least bring in some more variation.
