I don't believe there are any, except perhaps some obscure edge cases[1]. 
Every use for ACLs and extended attributes I've ever seen reduces down to the 
sysadmin gaining finer control over what other people can and cannot do on 
his system. On a single user work-station, the user IS the sysadmin, so the 
point usually becomes moot.

[1] For example, one might want a flag that can be set and unset on a file 
depending on the last action taken by some specific software. An archive 
attribute used by backup software would be the most well-known example. But 
this is certainly not the general case.
