Why is /afs mode 777 ???

[Randall S. Winchester]

Is there a good reason why /afs in not mode 555? 

Sendmail 8.9 is quite unhappy trying to work out of /afs/XXX as it appears
to be a world and group writeable directory.

I assume it is historical, and done before programs started looked at file
permissions. I know that it is an effective 555 directory.

Would anything break if this was "fixed" in an upcomming release?
