Not yet decided. There is the alternative to extend the accept()
interface to have both interfaces:

int accept(int, struct sockaddr *, socklen_t *);
and
int accept(int, struct sockaddr *, socklen_t *, int);

We can do this with type safety even in C nowadays.

If you read the mails of my first submission you'll find that I
explained this. I talked to Andrew and he favored new syscalls. But
then I talked to Linus and he favored this approach. Probably
especially because it can be used for syslets as well. And it is less
code and data than introducing new syscalls.
