It is the "new-format ciphername", which can be used for RSA keys if the 
new format file is being used, and is used for the elliptic curve keys, if 
I'm reading things correctly. I guess that would mean that it accepts 
things like "chacha20-poly1305_at_openssh.com" and "aes256-ctr" (see the 
table ciphers[] in cipher.c), though I don't know which ones make sense to 
pass in there.

I guess we should ask the OpenBSD folks to document it, the -Z argument 
was added to ssh-keygen.c in r1.237 back in December.
