It’s a fair point about the difficulty in deleting data in a decentralised system but that’s also true in more centralised systems like GitHub or any other website. Once some data is out there, you have no control over whether it can be removed. Other parties could have copied it and may re-share it. “All” removing data from a centralised system does is slow down this spread, sometimes to the point that it is effectively deleted but that can’t be guaranteed.

The best response I’m aware of is to invalidate any secrets that have been accidentally shared. Sometimes that is easier said than done though. And of course there are plenty of other reasons someone might want to delete data.

Well said, in particular the last sentence: IIRC at the time I was seeking to delete a repo that I had made accidentally so as to clean up my profile.
