They don't have to. Pattern matching is one of the first things they will learn, so they can use that instead.

They don't need to intuit it. The next version of base will have a warning on `head` telling them to use a safer alternative instead.
By the way, the Haskell community is currently struggling to accept that it should make fewer breaking changes, in order to become a more stable platform for industry use. We're definitely not going to start breaking more code!
