Steps to reproduce
When I use any FIDO device no matter if out of the box or already programmed I get an overwrite warning when adding new keys. On a new device you might just click away this warning. But on a "hot" device this leads to a lot of insecurity. Will it overwrite an existing key? It is a bad habit to get used to click away warnings.
So the suggestion is not to throw a warning when ssh-keygen does not overwrite anything.
Expected behavior
PS C:\Users\xyz\.ssh> ssh-keygen -t ed25519-sk -O resident
Generating public/private ed25519-sk key pair.
You may need to touch your authenticator to authorize key generation.
Enter file in which to save the key (C:\Users\xyz/.ssh/id_ed25519_sk):
Actual behavior
PS C:\Users\xyz\.ssh> ssh-keygen -t ed25519-sk -O resident
Generating public/private ed25519-sk key pair.
You may need to touch your authenticator to authorize key generation.
A resident key scoped to 'ssh:' with user id 'null' already exists.
Overwrite key in token (y/n)?
