I don't really want to veto it, but I'm not thrilled about it, because
I don't like introducing variables whose name is not provided by the
macro caller (and I find the benefit of things like `aif' rather small).

But maybe the new `if-let' (in subr-x.el) satisfies your needs:

  (aif E1 E2 E3) ~= (if-let ((it E1)) E2 E3)

Please submit those packages incrementally (say by groups of 1 million),
so we're not drowned.
