I'm going to assume you mean it is clearer without them, else I don't hear
an argument against beyond "I don't wanna".

For me, I don't see how::

  int x = do_something();
  if (x != 10)
    return NULL;
  do_some_more();

is any clearer or more readable than::

  int x = do_something();
  if (x != 10) {
    return NULL;
  }
  do_some_more();

I personally have come close to screwing up like this, but I caught it
before I put up a patch.

I honestly also prefer the consistency of just always using braces rather
than the sometimes rule we have. It isn't like C is a pretty, safe language
to begin with, so I would rather be consistent and avoid potential errors.
