Don't forget couple of things:
Dutch digid is tightly coupled with your address. All documents only go via regular post to your registered address in the Netherlands. No address? Moved to another one? Didn't register new address? Moved out of country? Good luck getting or updating digid.
Digid verification goes to your phone. Lost phone or get stolen? Changed mobile number? Guess what, no digid for you anymore.
You can just install and register a new Digid App it's not that complicated.
I mean people have physical passports and they sometimes lose those which doesn't seem to be a blocking issue.
