I'm not sure about your setup there, but if you mean that
/usr/local/opt/postgresql@13/bin is a symlink reading more or less
"./13.8/bin", I doubt that failing to canonicalize that is a good idea.
The point of finding the bindir is mainly to be able to navigate to its
sibling directories such as lib/, etc/, share/.  There's no certainty
that a symlink leading to the bin directory will have sibling symlinks
to those other directories.
