Those are all valid concerns.
Then, the digital passport's ship has already sailed for better or for worse, and all these questions are solved in other ways.
> when the Home Office messes up and accidentally deletes your immigration status
You're toast either way, because it will be checked at the airport. You'll have to deal with the immigration officer and have them do something, because you won't go very far with just a paper that will be checked against the backend. In my experience it has already been the case for a while now.
You still better have the reference paper that will help identify your visa procedure, dates etc. But it's already just a key to the info in the DB.
> you will no longer be in possession of any records
Print out the papers and keep track of the important pieces. It's the same for everything else in your life, including tax documents, birth certificates etc.
Even in the olden days, the papers you had only had value against the agency's record that could prove their validity. If you had to prove residency in some specific period, having a stamp on your passport would mean very little if the agency denied having any records of it. So it's exactly the same weight as if you printed out a certificate while the DB blew out and no data about it are left.
PS: I think in previous time people were also so much more lenient. It wasn't much a question of physical papers or not, and more on how much few people cared if your info was valid or not. I had an error in my name in many official documents, and while people noticed it, a simple "they typed it wrong" explanation was enough in 99% situations.
