Technically, you can call it with one argument.
But in 99% of the cases it's a really bad idea.

Exactly: it might make sense occasionally while debugging, but is
usually an error in code.
[ Using it with a second argument is quite different, because then it
  usually corresponds to a simple `remhash`.  ]

Which reminds me: I think it'd be better not to make it an alias.

Not sure what you mean with the "_not_ load" part, but as for `require`,
it's normal because it's preloaded.
