I'm guessing that whoever wrote arc-mode tried to avoid external tools as 
much as they could, since some of the wide-spread tools are not free 
software, and the free ones might not be installed.  Also, IIRC arc-mode 
allows you to edit the file's attributes in ways that might be 
impossible with external tools.

Anyway, if someone wants to rewrite those parts of arc-mode to use 
external tools, or perhaps fall back on that if the file's size is too 
large for Emacs, I'm sure that would be a welcome addition.

tar-mode _could_ do the same (i.e. use the external `tar' program).
