What?

I think you are confusing a couple of different things.  IIRC, at one
time when we were just thinking about ALTER TABLE RENAME, there was
a suggestion that the "real" table files be named by table OID, and
that there be symlinks to those files named by logical table name as
a crutch (:-)) for admins who wanted to know which table file was which.
That could be handled as you've sketched above, but I think the whole
proposal has fallen by the wayside anyway.

The current discussion of symlinks is focusing on using directory
symlinks, not file symlinks, to represent/implement tablespace layout.
