Looking at http://man.openbsd.org/tap.4 it seems like OpenBSD is indeed
supporting /dev/tap nowadays, so:
A question is what happens if we are using old version of OpenBSD which
does not have tap?
You can still specify the ifname manually, can't you?

Yes, but the codes were for cases that ifname were not given.
