5.2, slightly newer than 1.4T :), doesn't have it.

I would argue that it still needs pipe(2) to be converted into pipe(3)
with an xref to pipe2(2).

I'm guessing here, but my guess is that the syscall ABI (ie, the
interface at the kernel/user boundary) takes a pointer-to-two-ints (a
la socketpair) rather than expecting to get the ints via two return
values from the syscall.

That looks like one difference, from the diffs, and it also is pretty
much exactly what the stated problem is.
