Comment (by teor):

 I think this is "no backport".
 Here's why:

 Before this fix, exits that reject IPv4 but accept IPv6 are marked as
 "rejects all".
 After this fix, exits that reject IPv4 but accept IPv6 are marked as
 "accepts some".

 These exits are rare, so the change is not worth backporting.
