Comment (by anonymous):

 Seconded, being unable to pass permissions (and being unable to adjust the
 umask) opens an attack vector, with the directory being created with wide
 open permissions before being able to fix up the permissions. The
 following example illustrates the issue:
 {{{
   fs::create_directories(p);
   // There is a potential race here. Also note that
   // fs::permissions only fixes up the permissions for the last directory
 on the path.
   fs::permissions(p, fs::perms::owner_all);
 }}}

 Being able to pass permissions to create_directories would help with the
 race and would make it easier for developers to do the right thing (tm).
