There are people among us who practice Whateverism as an alternative to religion. But because of the nature of Whateverism, it's not expressed, discussed or promoted.
The core principle of Whateverism is having a lesser regard towards religion and not having a strong opinion about all or most of religious beliefs. Unlike atheism, it does not challenge religions or oppose them, it just ignores them. Another difference would be, unlike most atheists, Whateverists, do understand that intelligence, like any other thing, is relative and vary by the reference model, so they do not think of themselves as intelligent than the religious people.
Whateverists, do not necessarily associate moral values with religious believes. They take pride in that understanding, but do not socially brag about it; because they are content by what they are... :)
