I guess that it's mostly because attribute 
setting isn't portable across platforms 
(SysUtils.FileSetAttr always returns -1 on all 
Unix platforms and Dos.SetFAttr is simply ignored 
there). DOS-like (which includes Windows and 
OS/2) attributes are partly emulated for 
functions reading attributes, but their changes 
cannot be emulated meaningfully (well, it might 
be possible the other way round, i.e. emulating 
the more complex/complete solution for writing 
and the simpler one for reading, but the 
usefulness would be probably questionable.
