The case for symlinked directories being duplicated a lot isn't there, but there *is* a usecase for adding the symlink rather than the target, and that's homebrew. E.g. homebrew installs ruby into /usr/local/Cellar/ruby/2.7.1_2/bin, and links to it from /usr/local/opt/ruby/bin. If we add the target, we would miss updates. Having path entries that point to the same location isn't a big problem - it's a path lookup, so it takes a teensy bit longer. The canonicalization is mainly so paths don't end up duplicated via weird spelling and so relative paths can be used.
