I've not read anything other than the ssh-keygen manpage, but it says:
-m key_format
Specify a key format for the -i (import) or -e (export)
conversion options. The supported key formats are: “RFC4716”
(RFC4716/SSH2 public or private key), “PKCS8” (PEM PKCS8 public key)
or “PEM” (PEM public key). The default conversion format is
“RFC4716”.
I can't see a good reason not to use something that is widely documented
as opposed to inventing our own (even if the invention is very simple).
