Okay, then it's probably impossible to get correct behaviour with the
current design of pump if there's already another configured interface.

I've just tested the Hariguchi/Viznyuk dhcpcd a bit more systematically,
and contrary to what I thought first, it's working correctly (it uses
PF_PACKET sockets). Apologies to the authors. However, there's still
some problem if I try to use the -s option.
BTW, my patch also has the problem that it makes pump fail with kernels
that don't have support for SO_BINDTODEVICE enabled. While one could
just ignore the return code, this is ugly. Also, it may be possible to
have a kernel with the NAT problem but no SO_BINDTODEVICE, so there's
again no way to get it to work.
So I guess I agree - time to dump pump.
