Yes, this is safe to say. However note that ZMTP v2 and later use a
long length, and an empty identity, to handshake with older
implementations. So while the first frame must be 255 or shorter, that
length may be encoded in 1+8 bytes (not always 1).

The spec states that identities must be between 1 and 255 bytes and the first message in a ZMTP1 connection contains the id. So it’s safe to say that any first message with a length > 255 is an error?
