I don't see that cutting out an AM/FM radio is really going to save much money. Quite a few cheap phones and portable music players throw an FM tuner in as an essentially free bonus, meaning the technology cost is in the range of pennies.

So, since it's a long-standing tradition to have one in a receiver, it seems there's little need or desire to cut it out. Seems many preamps have one too, although they don't get a special name. :-)
