True, but the cache manager grants them special semantics above and
beyond the normal semantics of symlinks.  I'm curious about what
advantage that special treatment brings.

Is there any particular use-case that called for the
"xyz/mountpoint/../ == xyz" property which normal symlinks do not
have?  Are there any other properties mountpoints have which other
symlinks do not?
