There are many "non traditional" attributes that may be present.
ACLs, security contexts, extended attributes, capabilities, file system 
specific attrs, ...

OSX has added the -@ and -e options to output extended attributes
and ACLs respectively (on a separate line):

  $ /bin/ls -@eld /System
  drwxr-xr-x+ 4 root  wheel  136 Oct  9 07:53 /System
   0: group:everyone deny delete
  $ /bin/ls -@eld /Volumes
  drwxrwxrwt@ 3 root  admin  102 Mar  9 18:00 /Volumes
        com.apple.FinderInfo     32
   0: group:everyone deny 
add_file,add_subdirectory,directory_inherit,only_inherit

I do see some benefit to listing these attributes inline,
however I'm not convinced that we should add those, given that
there are separate tools to parse and display these items.
I.E. getfacl, getcap, getfattr, lsattr etc.
Given more attributes may be added in future, this is the most extendible 
scheme.
