We also have COW filesystems now. If you need large datasets in different places, used by different projects, etc, just copy them and use BTRFS or ZFS or whatever. It wont take any space and be safer. Git also has multiple ways of connecting external data artifacts. Git should by default reject symlinks.
Git itself (Or any other VCS for that matter) really should treat symlinks as special, similar as to how btrfs stores everything as "reflinks" internally. They be stored as special references to other tracked objects (so it'd be impossible to commit a symlink that pointed at anything other than a checked-in file, and ensure they always match), and git can materialise them as needed.
This is sadly not easily generalizable, since a lot of people still use legacy operating systems with filesystems like NTFS, which as far as I know is not COW.
