Well actually they'd see lots of drwxrwsr-x permissions i.e. write
permissions for group and they'd be more concerned about that. (until
they checked the group ownership and who was in that group)

(I'm still strongly in favour of it, though)

That's a little unfair -- I think there will legitimate
"please explains".

Some (many?) users _will_ want to know, so I think an explanation
is in order.  Merely reading the relevant man pages will typically
not be enough for the average user.

The fact that some of the readers of this list required an
explanation is an argument _for_ including an explanation
somewhere in the debian docs.  Presumably those reading this list
are more unix-clueful than your average unix/linux user.
