I am talking about simple truncation (leftmost 200 bits (25 octets)) of
SHA-256/512 similar to what Git does.  I explained the reason in my
reply to Jon's suggestion for SHA-512/t: This will make it easy to get
rid of the truncation iff need arises - without defining a new key
format.  That is the full fingerprint will be the same and searches for
the truncated or full fingerprint will still return the same key.
