This doesn't cause a problem, you can simply generate an RSA key if you would like to use a key to connect to a system that does not yet support ed25519 keys. Using ed25519 by default is also a gentle nudge to vendors (maybe it will become easier for them to add support than explain to users how to generate an rsa key).
