There is no issue on the tracker and he apparently never did.
There is a general policy of lightly wrapping useful os calls in os.
Martin said this already in what was essentially a 'go ahead'.
Problems include os differences,
The only difficulty I can see is the choice of name for the wrapper.
IMO, using "sendfile" from Linux and FreeBSD is pretty much okay; but
objections may arise.

such as name differences (but I think *nix generally wins ;-),
and the need for 'someone' to write the patches for the appropriate
C-coded os files: posix, nt, os2, ce. Patch write makes initial decision
on ironing out differences.
The above was the second and last substantive answer to Andrew, as there
was nothing much more to say.
The tracker awaits ;-). Specify, if you can, whether you think the
windows TransmitFile or modern equivalent is sufficiently compatible
with the *nix sendfile to be wrapped with the same API or whether you
propose Availability: Unix only.
