Martin Storsjo tried the same approach already, and it was rejected. If I
remember correctly separate wrapper functions were preferred in this case.

It looks like Alexandre said "It would be better to create a separate
function, unless there is strong evidence that they are doing the
exact same thing." [1][2]

There is strong evidence that they are doing the exact same thing, but
if you need me to write a test case to provide ironclad evidence, I
can do that.
