On my Ultra 25 with Solaris 10 and every other Solaris 10 box, they
just have the two MIT copyright files.

Same here. Symlinks to a .Dotfile directory. Messy but works.
(My home directory has been in AFS since 1992.)
But until this general problem can be solved on *all* platforms
one can not tighten down the ACLs on the home directory. Maybe
get Sun do somehting about it on their systems. NFSv4 should
have the same problem, so maybe they will.
