Well, if you model can tell guess my name from 100 browser history entries, then yes, I want the law to require you to retrain your model once I invoke that right. An interesting matter is a use of blockchain-like scheme. I guess the law would mean you can't put GDPR protected information in a public distributed blockchain, but instead use identifiers to decouple GDPR info from that ID. And the invocation of that right to be forgotten would require us to permanently delete an entry linking that identifier to a user.
