I can think of a potential solution for this issue:
Create something new which is like symlinks, but which has its own permissions. Since these permissions would allow things that would otherwise be impossible (otherwise, what's the point?), a few restrictions would be necessary. For example:
[a] if permissions are satisfied, you get to act as the owner of the link for the purpose of file access, nothing more.
[b] to reduce the scope of this card, the directory which holds the target file must have a special bit which says that its files may be accessed this way, and every parent directory must have a different bit which says that this is possible.
This might also be used as part of a scheme to seal up the static parts of proc.
