Sounds like this could be solved by redirects? Sure, may get a little confusing if/when someone takes that username after it was abandoned but it seems worth the trade given the implementation. Really it depends on how they're handling the links. I'm not a web person so this may be very naive, but it definitely seems like a solution is that all handle-based links are really just proxies for DID based links. If they're all DID on the backend, then I don't see the problem. You're just building a growing ledger (which is happening anyways and seems like a bigger problem). Of course I'm willing to acknowledge my naivety here and wouldn't be surprised if I'm working with a bad mental model that's leading to poor solutions. If this is a terrible solution I'd appreciate the learning opportunity so I can better understand.
