..., even in cases where a different keypair succeeds later on, threaten to hose applications that expect the connection to be transparent (or fail completely)? As in, rsync, git, etc.? In general, the client may try a number of keypairs and every try has a number of possible reasons to fail, from cryptalgorithm-related ones (including "cipher (here: RSA) rejected" and "hash (here: SHA2 variant(s)) rejected") to "unknown keypair" to less-frequent ones (like "pubkey has a ForceCommand option and I can't execute that" etc.). I don't think that we should try...

An issue that I come across from time to time is when I try to ssh into a box with an RSA key, and it fails because the target host is old and only does sha1 signatures.? However, the reason is not reported unless I turn on debugging. For example, all I see is: % ssh foo at bar foo at bar: Permission denied (publickey,keyboard-interactive). I find this confusing, since my first inclination is
