There are places in the kernel that would like to have access to `pgid` credentials in certain circumstances. I haven't found any use cases for `sid` yet, but `sid` and `pgid` are both changed with `sys$setpgid`, so it seemed sensical to add it. In Linux, `man 7 credentials` also mentions both the session id and process group id, so this isn't unprecedented.
