However, experience from the last few years seems to suggest that including desired options is only half the story. The other half is excluding options that are not wanted.
The warlord class. The tiefling and dragonborn races. The come and get it power. Even though the game might have options they want, the fact that it also includes options that they don't want seems to be a sticking point for some people.
The nature of a dial is that you can turn it up or down. The reason people objected so much to tieflings, dragonborn, and warlords is that they were in the core PHB, which implies they are "present by default." You have to go out of your way to exclude them, and the electronic tools offer no support for it.
As Rechan says, if stuff like this gets moved off into its own book, it's more palatable.
