Yes, but the symlinks are typically not installed by default, since they’re not required for using the libraries, only for building against them.
But mainly, what happens if someone has multiple versions of the library installed? Perhaps the symlink points to libtree-sitter-foo.so.16, but we’re linked against a version of Tree-sitter that support libtree-sitter-foo.so.15 at best. It seems to me that, since we know what versions we support, we may as well start with libtree-sitter-foo.so.15, rather than loading libtree-sitter-foo.so and hoping for the best.
