It would be possible but also potentially break links that look like tracking but isn't. Also there's a way for the trackers to bypass it by designing links differently anyway, so it would still slipp through.

URL shorteners track by hashing the main link and work as a tracker in the middle.

I think I remember having heard that facebook links by standard are hashed tracking links. => They always look like random mumbo jumbo, and have their tracking embedded in their own systems by a ledger.
