Surely worst than a bug, this maybe be a lack a collaboration between coreutils 
and acl teams, or an underlying religion war. A more positive scenario could be 
that the teams discovered some security issue (or a crippling performances one) 
we're not aware about if cp/mv/tar etc... would ever check for a default acl 
and trust/rely acl to set mode bits when they find one (although, mkdir and 
touch reach the goal, but they do pure creation). Whatever I feel now that my 
linux box is just a techno-toy, not even suited for a family usage, at best a 
multi alternated single-user OS.
